Abstract

This paper investigates the problem of cracks emanating from a circular hole in an orthotropic infinite plate. The mixed-mode sterss intensity factors are obtained by using the modified mapping-collocation method. To investigate the effect of anisotropy and circular hole of the normalized crack length for various types of laminated composite. The results indicate a strong dependence of the stress intensity factor on the material anisotropy and geometry.
