Strength tests were performed to reveal the failure mechanisms of spot weld in lap-shear and cross tension test samples. It is shown the while the lap-shear (cross tension) sample is subjected to shear (normal) load at the structural level the failure mechanism at the spot weld is tensile (shear) mode at the materials level. Based on the observed failure mechanism, stress distribution is assume...
The paper describes a program of mechanical testing on donated human eye bank lenses. The principal purpose of the tests was to obtain experimental data on the shear modulus of the lens for use in future computational models of the accommodation process. Testing was conducted using a procedure in which deformations are induced in the lens by spinning it about its polar axis. Shear modulus data ...
A large number of cyclic torsional shear tests on saturated soft clay under unconsolidated undrained condition have been carried out. The changing law between accumulative generalized shear strains vs. failure numbers has been analyzed and a cyclic shear strength curve has been received based on cyclic torsional shear tests. According to the test results, the criterion of saturated soft clay is...
Shear stress is an important parameter in estimating the slope stability and flow dynamics mass movements. The ring shear test can often be employed to determine residual because of its suitability for large deformations assumed situ drainage conditions. Determination weathered landslide materials composed coarse-grained sediments was examined with respect displacement condition. Based on exper...
STUDY DESIGN A comparison of cervical facet capsule strain fields in cadaveric motion segments exposed to whiplash-like loads and failure loads. OBJECTIVES To compare the maximum principal strain in the facet capsular ligament under combined shear, bending, and compressive loads with those required to injure the ligament. SUMMARY OF BACKGROUND DATA The cervical facet capsular ligament is th...
A new nonlinear constitutive model for the three-dimensional stress relaxation of articular ligaments is proposed. The model accounts for finite strains, anisotropy, and strain-dependent stress relaxation behavior exhibited by these ligaments. The model parameters are identified using published uniaxial stress-stretch and stress relaxation data on human medial collateral ligaments (MCLs) subjec...
