Abstract:
This paper presents a series of cyclic uniaxial compressive loading tests carried out on cylindrical samples of bamboo, in order to develop unloading and reloading stress-strain models. Two bamboo species from Congo Basin, the Bambusa vulgaris and Oxytenantera abyssinica were used for these experiments.   It is found from the test results that the unloading and reloading do not essentially change the shape of the envelope curves of the stress-strain relations and that to predict models for an unloading and a reloading path, the plastic strain, the unloading strain, the strain at yield, th

Abstract:
Sequences of fatigue-tension tests were performed on copper polycrystal sheet, with 32µm mean grain size. The effect of strain path change on subsequent reloading yield stress as well as work hardening rate has been investigated. Dislocation microstructure was observed by transmission electron microscopy after mechanical tests. Under present conditions, it was found that fatigue prestraining caused the increase of reloading yield stress, larger amplitude of strain path change resulted in higher reloading yield stress and lower work hardening rate. Reloading tensile curves are independent of pr

Abstract In order to improve the efficiency of rapid replenishment of chainless ammunition feeding system, the dynamics simulation analysis of the movement relationship between the driving sprocket and the shell and the handover relationship between the toggle wheel and the shell in the replenishment device is carried out for the replenishment device of chainless ammunition feeding system as an object.

Abstract:
We have extended the micromechanics-based analytical (M-A) model to make it capable of simulating Nuozhadu rockfill material (NRFM) under different stress paths. Two types of drained triaxial tests on NRFM were conducted, namely, the stress paths of constant stress ratio (CSR) and the complex stress paths with transitional features. The model was improved by considering the interparticle parameter variation with the unloading-reloading cycles and the effect of the stress transition path. The evolution of local dilatancy at interparticle planes due to an externally applied load is also discusse

Abstract:
The aim of the paper is to extend the experimental validation of the S-CLAY1 model, which is a recently proposed elastoplastic constitutive model that accounts for initial and plastic strain-induced anisotropy. Drained stress path controlled tests were performed on reconstituted samples of four Finnish clays to study the effects of anisotropy in the absence of the complexities of structure present in natural undisturbed clays. Each test involved several loading, unloading, and reloading stages with different values of stress ratio and, hence, induced noticeable changes in the fabric anisotropy

Conventional depth-sending indentation and novel cyclic indentation were performed to study the mechanical properties and strengthening mechanism of pure gold and Ca-doped gold of up to 90 ppm. The system was chosen because it is popular materials for microelectronics interconnection, yet the strengthening mechanism is not well-understood. Conventional depthsensing indentation showed an increase in hardness and modulus of gold with increasing Ca content of up to 90 ppm, which remained significantly higher after annealing.

Abstract:
A novel damage model for concrete has been developed, which can reflect the complex hysteresis phenomena of concrete under cyclic loading, as well as other nonlinear behaviors such as stress softening, stiffness degradation, and irreversible deformation. The model cleverly transforms the complex multiaxial stress state into a uniaxial state by equivalent strain, with few computational parameters and simple mathematical expression. The uniaxial tensile and compressive stress–strain curves matching the actual characteristics are used to accommodate the high asymmetry of concrete in tension and c

Abstract:
Abstract Recent biaxial experiments on spruce wood show that consideration of an elliptic failure surface according to Tsai and Wu and an elastic model for stress states within this envelope lead to an insufficient description of the mechanical behavior. As compression perpendicular to the grain occurs, a non-linear stress path results from a proportional biaxial strain path. Investigation of characteristic samples with respect to loading-unloading-reloading cycles for states of stress below failure reveals behavior similar to what is known as hardening type plasticity.

This study aims to evaluate the relevance of the active plasticity hypothesis in predicting the risk of cleavage fracture during a WPS loading cycle. We define a critical loading path, along which the active plasticity hypothesis might fail. On this critical loading path, Beremin local model is compared to a stress-based criterion model. The chosen critical loading path is a LTF (Load-Transient-Fracture) cycle, including an isothermal preloading up to F1WPS = 42 kN at TWPS = −25°C followed by a cooling down to TFRAC = −150°C with a progressive loading up to F2WPS = 45 kN before an isothermal r

The Reactor Pressure Vessel (RPV) is an essential component, which is liable to limit the lifetime duration of PWR plants. The assessment of defects in RPV subjected to pressurized thermal shock (PTS) transients made at an European level generally does not necessarily consider the beneficial effect of the load history (Warm Pre-stress, WPS). The SMILE project — Structural Margin Improvements in aged embrittled RPV with Load history Effects — aims to give sufficient elements to demonstrate, to model and to validate the beneficial WPS effect.

The generalized effective plastic strain increment is derived to accommodate various yield criteria.

The plastic deformations are described by the introduction of the yield and the flow directions. These directions do not agree, which reproduces the non-associated feature of realistic soils.

This study investigates the applicability of the hypoplastic model in predicting the mechanical behaviour of sand under both monotonic and cyclic loading conditions. Monotonic loading conditions are explored to comprehend the soil's strength and deformation characteristics, while cyclic loading conditions are crucial for understanding the soil's response under repeated loading, particularly its behaviour during the unloading and reloading phases.
