Paper Abstract

The stress-strain fields for composite laminate [±25]S4 containing a circular hole under uniform axial extension are investigated using numerical and experimental methods in this paper. The distributions of normal strain along the length direction around the hole on the specimen surface are measured using digital speckle correlation method (DSCM). Meanwhile, only the middle part of the laminate is taken into account to perform finite element (FE) analysis. For the side face of specimen, a tiny area (1.8mm x 2.4mm) over the hole is chosen to measure the normal strain and shear strain. The experimental results are in a good agreement with FE simulation. Additionally, the interlaminar stress analysis on the hole edge has been performed by FE method.
