| Research Abstract |
The experiments of thin rectangular plate reinforced by L-shaped ribs under the action of bending are carried out to investigate the large deformation behaviors as well as the impacte strenght, and compared with the finite element solutions. The constitutive equation for dynamic plasticity is proposed by extending the internal time theory of static plasticity, and the finite element analysis for the large shear deformationis carried out.
