Abstract:
Measurement of the tensile properties of high strength woven and knit fabrics, including geotextiles and geogrids traditionally make use of roller grip-type clamping systems. These grips are designed to allow a sample to be pulled in tension without applying an excessive crimping or compressive force on the specimen, thus avoiding premature failure. Roller grips, also known as capstan grips, also have the advantage of allowing the specimen to align itself with the applied force therefore loading the specimen uniformly across the width. However, since the specimen tightens itself around the gri

Abstract:
Hand grip strength (HGS) is a useful functional measure of the integrity of the upper extremities, however, many studies have examined it from selected positions (i.e., supine, sitting, standing), with no emphasis on other derived positions that are used in clinical setting. This study’s objective was to evaluate HGS in different body positions that are used in clinical setting by using a standard protocol. The study sample was a convenience sample of 40 healthy male participants with no history of psychiatric, neurological, or upper extremity orthopedic dysfunction. Grip strength in the domin

The objective of this study was to investigate the test–retest reliability of measurement of grip strength in full elbow extension. The grip strengths of 19 healthy participants were measured using the Jamar dynamometer by the same rater on two occasions with an interval of 7 days between measures. Test–retest reliability of grip strength measurement was excellent in full elbow extension and associated with low values of standard error of measurement and small variations in the differences between the two measurements in both testing sessions.

This study assessed the use of rapid, repeated measurement of grip strength to detect feigned hand weakness. Normal participants, performing with maximum effort or feigning hand weakness, and patients recovering from carpal tunnel surgery were asked to grip a Jamar dynamometer alternately with each hand on ten occasions. The results showed that grip strength fatigued by an average of 23% during the test in the normal participants, 18% in participants faking weakness, and increased by 2% in the carpal tunnel decompression patients.

Detecting submaximal effort when testing grip strength is difficult. Research so far has focused on the discrimination between sincere and feigning healthy participants, whereas the clinically relevant distinction is between injured patients and feigning participants. The aim of our study was to compare rapid exchange grip and isometric grip strength testing in 41 participants feigning weakness with 39 patients with decreased hand function. Various parameters that describe grip strength were recorded and tested for differences between the groups. Only the maximum grip strength during rapid exc

Abstract:
The application of composite materials for prosthetic applications is the norm in recent times. Accurately characterizing the principal stresses during tensile testing is therefore essential. The low transverse compressive strength of most composite materials limits high clamping forces during tensile testing. Tabs are consequently critical for cushioning against grip pressure and surface damage. However, tabs tend to introduce induced stress concentrations. In this chapter, the induced stress concentrations are minimized via the optimization of tab design configurations. Stress concentration obtained via finite element analysis were used to develop a full factorial design for statistical analysis and compared with a Taguchi, Taguchi-multi response and Taguchi-genetic algorithm optimizations. It was established that to minimize the stress concentrations, low values of tab stiffness, thickness, and taper angle were required while the adhesive thickness was increased. The Taguchi and hybrid approaches were efficient and reduced the number of simulations from 32 to 8 (75% reduction).

Abstract:
Smart grids provide a digital upgradation of the conventional power grids by alleviating the power outages and voltage sags that occur due to their inefficient communication technologies and systems. They mainly tend to strengthen the efficiency, performance, and reliability of the traditional grids by establishing a trusted communication link between their different components through routing protocols. The conventional methods, i.e., the computer-based simulations and net testing, for analyzing these routing network protocols are error-prone and thus cannot be relied upon while analyzing the safety-critical smart grid systems. Formal methods can cater for the above-mentioned inaccuracies and thus can be very beneficial in analyzing communication protocols used in smart grids. In order to demonstrate the utilization and effectiveness of formal methods in analyzing smart grid routing protocols, we use the UPPAAL model checker to formally model the ZigBee-based routing protocol. We also verify some of its properties, such as, liveness, collision avoidance and deadlock freeness.

A uniaxial tensile test is a useful method for determination of material properties, especially longitudinal tensile strength. To accurately derive the longitudinal tensile strength, it is desired that the specimen fails in in the gauge section defined here as ‘working zone’. Unidirectional (UD) composites require use of end tabs during this tensile testing to avoid damage to the specimen due to grip serrations. The grip pressure, along with sudden geometry change at the edge of end tabs leads to longitudinal stress concentrations. The conventionally used rectangular and tapered end tabs suffe

Abstract:
The solder ball shear test is a commonly used method to evaluate the attachment strength of solder balls. However, some previous studies indicated that the solder ball shear test may not be suitable for showing the effect of intermetallic compound (IMC) growth due to thermal aging. This is because the IMC layer is thin and not susceptible to the shear loading. Since the IMC layer consists of brittle materials, the ball pull test should be a better method to evaluate the solder ball attachment strength. The major challenge of conducting a solder ball pull test is how to grip the solder ball. Th

There have been numerous operating experience events where socket welds have developed cracks due to high cycle fatigue. On the other hand, parts of compression joints plastically deform the pipe to grip and create their sealing c
