Abstract:
Combined with Jones-Nelson-Morgan model applied to ceramics and graphite successfully, the nonlinear constitutive model of concrete is obtained through large number of tests in this paper. The model takes concrete as nonlinear elastic isotropic material. By using strain energy function, it makes the nonlinear mechanics behavior of concrete as the function of strain energy. According to the mechanics behavior of concrete, a simple model is obtained by increasing stress to realize the model calculation program. The model can be extended to the constitutive model analysis of concrete under biaxial stress. The theoretical model conforms to testing results well.

Full text
Abstract:
Most heat resisting materials in structural components are used under multi-axial stress conditions and under such conditions ductile materials often exhibit brittle manner and low creep ductility at elevated temperature. Creep crack initiation and growth properties are also affected by multi-axial stress and it is important to evaluate these effects when laboratory data are applied to structural components. Creep crack growth tests using circumferential notched round bar specimens are a simple method to investigate multi-axial stress effects without using complicated test facilities. Creep crack growth tests have been performed using a 12CrWCoB turbine rotor steel. In order to investigate the effects of multi-axial stress on creep crack growth properties, the tests were conducted for various notch depths at 650°C. The circumferential notched round bar specimen showed brittle crack growth behaviour under multi-axial stress conditions. Creep crack growth rate was characterized in terms of the C* parameter. A 12CrWCoB turbine rotor steel has been tested using circumferential notched round bar specimens with different multi-axiality. Circumferential notched round bar specimens show increased brittle creep crack growth behaviour due to the multi-axial stress condition. Creep crack growth properties could be predicted by allowing for the decrease of creep ductility under multi-axial conditions.

Abstract:
The purpose of this study was to evaluate the efficacy of multi-axial (lateral + vertical) active suspension in reducing multi-axial WBV exposures and related biomechanical loading in the neck and low back as compared to an industry standard single-axial (vertical) passive suspension seat. In a repeated-measures laboratory study with 13 subjects, while recreating field-measure vehicle vibration on a 6-degree-of-freedom motion platform, we measured WBV [weighted average vibration: A(8) and vibration dose values: VDV(8)], net joint torque in the low back (L5/S1) and neck, muscle activity in low back (erector spinae) and neck muscle (splenius capitis). The results showed that the multi-axial active suspension seat was more effective in reducing vertical (Z-axis) WBV [A(8) and VDV(8)] as compared to the single-axial passive suspension seats (p < 0.001), while little difference between two suspension seats were found in lateral (Y) axis. The peak low back moment with respect to the sagittal (Y) axis was significantly lower on the multi-axial active suspension seat compared to the single-axial passive suspension seat (p=0.01). Despite lack of statistical significance, the low back and neck muscle activity tended to be lower on the multi-axial active suspension compared to the single-axial passive suspension. These results indicate that the multi-axial suspension may have potential to reduce biomechanical loading in the low back.

Abstract:
In order to investigate the multi-axial mechanical properties of a kind of PU (polyurethane) foam, some experiments in different loading conditions including uni-axial tension, uni-axial compression, hydrostatic compression and three-point bending were conducted. It is shown that the hydrostatic component influences yield behavior of PU foam, the yield strength and degree of strain hardening in hydrostatic compression exceed those for uni-axial compression. In terms of the differential hardening constitutive model, the evolution of PU foam yield surface and plastic hardening laws were fitted from experimental data. A finite element method was applied to analyze the quasi-static responses of the PU foam sandwich beam subjected to three-point bending, and good agreement was observed between experimental load-displacement responses and computational predictions, which validated the multi-axial loading methods and stress-strain constitutive model parameters. Moreover, effects of two foam models applied to uni-axial loading and multi-axial loading conditions were analyzed and compared with three-point bending tests and simulations. It is found that the multi-axial constitutive model can bring more accurate prediction whose parameters are obtained from the tests above mentioned.

To find out the cause for fatigue failure of a drill string used in oil field drilling, and considering the actual working conditions, axial, radial and circumferential cyclic stresses borne by the drill string in borehole of oil and gas well, fatigue strength of drill string is analyzed based on multi-axial fatigue assessment method. Then the formula to calculate the mean stress of multi-axial load of the drill string is obtained, and the formula serves as a method to calculate multi-axial fatigue life of the drill string, which has been verified through field data. It is realized that multi-axial stress has significant influence on drill string fatigue. When on drill string fatigue, Soderberg equation shall be employed to calculate the stress amplitude of drill string fatigue.

Abstract:
This paper focused on the tensile performance of PVC-coated membrane materials under multi-axial loads. Several groups of experiments were carried out to investigate the effect of the specimen configuration and the loading speed on the tensile properties. It could be concluded that the configuration of the specimen plays an important role on the tensile performance of the materials. The suitable configuration for multi-axial loading tests had been identified. It was also found out that the loading speed had certain effect on the tensile failure performance and the tensile response. A loading speed of lower than 20mm/min was suggested to achieve a reasonable result of the multi-axial tensile performance of PVC-coated membrane materials. Another group of tensile experiments with a crack in the center of the specimens under multi-axial loads were performed. It was noticed that the tensile properties in warp direction of the coated membrane materials play an important role in the tensile failure under multi-axial loads, no matter the initial crack length and the crack orientation are.

Abstract:
The stereo dissecting microscope is a widely used instrument for macro-structure observation and documentation. The emergence of digital imaging, along with sophisticated imaging software, makes this macro-imaging more efficient. It also makes possible certain special imaging modes that are difficult to accomplish with traditional (film) imaging, such as extended depth of focus imaging ( EDF), automatic mont aging, etc. These special imaging techniques often require dedicated hardware on the microscope, such as a motorized stage.

Abstract:
Pulmonary Embolism (PE) is a respiratory disease caused by blood clots lodged in the pulmonary arteries, blocking perfusion, limiting blood oxygenation, and inducing a higher load on the right ventricle. Pulmonary embolism is diagnosed using contrast enhanced Computed Tomography Pulmonary Angiography (CTPA), resulting in a 3 D image where the pulmonary arteries appear as bright structures, and emboli appear as filling defects, with these often being difficult to see, especially in the subsegmental case. In comparison to an expert panel, the average radiologist has a sensitivity of between 77% and 94 % . Computer Aided Detection (CAD) is regarded as a promising system to detect emboli, but current algorithms are hindered by a high false positive rate. In this paper, we propose a novel methodology for emboli detection. Instead of finding candidate points and characterizing them, we find emboli directly on the whole image slice. Detections across different slices are merged into a single detection volume that is post-processed to generate emboli detections. The system was evaluated on a public PE database of 80 scans. On 20 test scans, our system obtained a per-embolus sensitivity of 68% at a regime of one false positive per scan, improving on state-of-the-art methods. We therefore conclude that our multi-slice emboli segmentation CAD for PE method is a valuable alternative to the standard methods of candidate point selection and classification.

The grain refinement mechanism and texture evolution of Mg-7Gd-5Y-1Nd-0.5Zr alloy during multi-axial forging have been investigated.

Abstract:
In this paper, a non-mechanical axial zoom scanning method based on a phase only liquid crystal spatial light modulator is proposed. This novel method is to overcome the measurement error caused by moving mechanical parts in the axial mechanical scanning methods in the confocal microscopy system. The modulation on the incident wave front is completed by a spatial light modulator, which provides this scanning method some outstanding advantages including the flexibility of control and the absence of moving mechanical parts, especially suitable for the fixed sample imaging occasions. By simulating the multiple Fresnel lens with LCSLM to generate controllable multi-focal points and thus realizing this method of axial multi-focus scanning to enhance the axial scanning efficiency and the range. Simulations and experiments on the axial scanning features of the axial multi-focus zoom scanning method are carried out. Results of simulations and experiments indicate that non-mechanical axial zoom scanning can be realized with the use of a spatial light modulator in the confocal microscopy system.
