Energy dissipation-based arc-length method for nonlinear response prediction

Energy dissipation-based arc-length method for nonlinear response prediction  

Md. Alhaz Uddin

The nonlinearity induced by the large deformation or material nonlinearity or both responses is manifested in the form of nonlinear load-deflection curves. These curves can have a descending branch after attaining the peak load due to the strain-softening behaviour of materials in its inelastic range. The solution of this typical nonlinear finite element problem is quite challenging and a load control-based technique cannot trace the descending branch of the load-deflection curve. In order to overcome this problem, a displacement control-based technique may be used; however, this will also fail if the load-deflection curve has a snap-back response. In this situation, an arc-length based solution technique seems to be the only possible option...
