Tensile and fatigue properties of as-rolled and annealed polycrystalline Cu foils with different thicknesses at micrometer scale are investigated. Uniaxial tensile testing shows that with decreasing foil thickness the uniform elongation decreases for both as-rolled and annealed foils, while the yield strength and ultimate tensile strength increase for as-rolled foils, but those decrease for the...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

We use a continuum model to investigate the isochoric axial contraction and expansion of a right circular cylindrical specimen composed of a nematic elastomer that is cross-linked in a uniaxial state and then annealed. We build on previous work by relaxing the constraint that the molecular conformation be spherical or uniaxial, allowing instead for biaxiality. The material exhibits an energetic...
