摘要
A dual-horizon peridynamic (DHPD) model with arbitrary horizon sizes and shapes is proposed for predicting structural responses of thin-walled structures subjected to out-of-plane loadings. The proposed DHPD method can diminish the influence arising from ghost forces in irregular particle distributions and lessen the computational consumption with optimal refinement discretizations. Meanwhile, the variable PD parameters of each discrete particle that derive based on its own current horizon domain are adopted to mitigate the PD surface effect. Several static and dynamic structural responses with different geometric and boundary conditions are compared between the reference and DHPD approaches. It is concluded that the proposed DHPD method can effectively reproduce structural behaviors in fracture mechanics problems with less computational effort.
