Stress-strain relations of SUS304 after cyclic preloading.

On the Structure of the Stress-strain Relations.

A Strain Range Dependent Cyclic Plasticity Model

Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...

Numerical investigation of strain distribution during cyclic expansion extrusion (CEE)

Strain distribution of Al 1100 was numerically investigated during cyclic expansion extrusion (CEE) process using finite element method (FEM). Die angle, corner fillet radius and die chamber diameter were considered as die parameters and friction factor and number of passes as process parameters. The effects of these parameters were investigated on the effective strain and strain homogeneity in...

Stress-strain relations for crystals containing plastic deformation.

Let P be one of the possible slip planes in a crystal, and let X be one of the possible slip directions in the plane P. Also let S be the magnitude of the shearing stress on the plane P resolved in the direction X, and So the critical value of S, i.e., the least value of S sufficient to permit slip or plastic deformation under the conditions specified in the following italicized statement; if s...

an investigation of stress-strain behavior of frp-confined concrete under cyclic compressive loading

one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...
