A bond-based peridynamic model was developed to study in-plane dynamic fracture process in orthotropic composites. The peridynamic material constant was extended to a continuous micromodulus C θ for orthotropic materials. C θ changes continuously f

Delamination is one of the severest failure modes for laminated composite materials during applications, especially when the composites are subjected to dynamic loading like impact. The impact-induced delamination patterns in laminates have been stud

The nonlocal peridynamic theory has been proven to be a promising method for the material failure and damage analyses in solid mechanics. Based upon the integrodifferential equations, peridynamics enables predicting the complex fracture phenomena suc

Measuring impact-induced contact force history is critically important to understanding the nature of impact events and the associated damage processes of materials/structures involved in the impact. In order to investigate the impact-induced contact

To develop a composite with high in-plane properties and sufficient delamination resistance, a quasi-three-dimensional (Q3D) woven composite has been designed. In Q3D, some yarns in each layer are woven into those in the adjacent layers and form a 3D

Dynamic fracture in single-edge notched polymethyl-methacrylate (PMMA) beams have been investigated by three-point-bending impact testing with a drop-weight machine. A high-speed camera combined with the digital image correlation (DIC) method is used

Peridynamics (PD) is a nonlocal form of continuum mechanics theory. It has advantages in simulating damage and fracture problems. In this paper, a twodimensional bond-based peridynamic model has been extended into three-dimensional for laminated comp

Drop weight impact testers (DWIT) are commonly used in experiments for characterizing material properties and structural performance. With large mass, DWIT can provide large impact energy. However, the impact velocity involved in DWIT is usually low
