Abstract
An analytical method for predicting the elasto-plastic bending of rectangular plates with large deflection is studied. The concept of equivalent body force is applied to account for the plastic strain gradients and the non-linear terms of displacement derivatives. The calculated deflection for purely elastic plates compares well with other existing solutions. The deflection is increased slightly by plastic strain; however, the stress is considerably relieved by plastic yielding. Nuclear Quadrupole Resonance(NQR) on dilute inert fillers in several polymers and adhesives is made as a function of compression and tension. The change in the NQR response is found to be proportional to the strain applied to the host material. NQR measurements on reinforced polymers and adhesive bonds are reported. (Author)
