This elastic–plastic model, coupled with the intralaminar damage criteria, has been employed to simulate the nonlinear behavior of FRP composites under the impact load. The elastic–plastic model may perform the same as the elastic model under lower energy impacts, while the elastic model cannot ...
? Stereo vision was used to measure the crack‐tip parameters, such as J integral, plastic mixity and elastic mixity of mixed‐mode fracture specimens, and to study the applicability of the Shih's plane strain solution to the mixed‐mode crack‐tip fields. The fracture specimen used in ...
A semi-analytic inelastic Timoshenko beam theory based on a modal solution is developed. Inelastic strains are equivalent to eigenstrains in an identical but entirely elastic background structure. Proper resultants of these eigenstrains, i.e. inelastic curvatures and averaged inelastic shear angels, ar...
This differential ratio can be used to represent the damage degree and damage evolution. Based on this, the damage model based on differential ratio of elastic plastic dissipated energy is proposed, and the specific calculation methods under monotonic static load, quasi-static load and dynamic load...
The physical aging of amorphous solids is crucial for understanding their glass transition, mechanical deformation, and crystallization behavior, with the core focus on constructing aging models to elucidate relaxation mechanisms and predict the evolution of their mechanical and physical properties. This stu...

This is because the model could not consider the plastic strain of the material, the evolution of the material damage and the development of the cracks.

9.2 Analysis of elastic-plastic structures In Section 4.2, the elastic-plastic behavior of cross sections were discussed and for a few cases the moment-curvature diagrams were calculated. An example is shown in Fig. 9.6a. Often idealized curves are used: elastic-plastic (Fig. 9.6b) or sometim...
