Bending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition
The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

متن کاملGeneralized plane strain deformation of multilayer structures with initial strains
A closed-form solution for multilayer structures with initial strains under generalized plane strain conditions is presented. Such solutions can be useful for estimating the curvature radius and strains or stresses for self-positioning microand nano-structures with lattice mismatched layers. Comparison with finite element results shows that the developed solution predicts reasonable values of t...
متن کاملA well-posed finite-strain model for thin elastic sheets with bending stiffness
An accurate, well-posed two-dimensional model incorporating stretching and bending effects, suitable for analyzing the wrinkling pattern in stretched sheets, is derived from three-dimensional nonlinear elasticity theory.
متن کاملBending waves in crumpled sheets.
Crumpled paper has recently emerged as a model for disordered media. Here we use wave propagation to probe aluminum foils crumpled into balls made by hand or into cylinders obtained by confinement in a container. Surprisingly, the raw dispersion relations appear to differ from sample to sample. They correspond to bending waves that follow an effective path that is shorter than the distance betw...
