| Abstract: |
| Peridynamic(PD) theory is formulated by means of integral equations,as opposed to partial differential equations that include derivatives of displacements in the classical continuum theory.Therefore it is well-suited for any kinds of problems concerning discontinuities without any assumptions.In this paper,a PD model for orthotropic lamina is firstly proposed.Then the composite laminate PD model as well as its damage model is introduced by considering an interlayer interaction between layers.Finally,a comparative simulation of impact damage for isotropic and orthotropic laminates is carried out to verify the effectiveness of the present approach. |
