Description

Orthotropic plates are analysed by the boundary element method with the fundamental solution of Cruse and Swedlow and isoparametric elements. The stress concentration factors and stress intensity factors are obtained for three kinds of materials, that is, glass fiber reinforced plastics, carbon fiber reinforced epoxy and oak timber. The calculations are carried out for some sizes of the circular hole or crack. Part of the numerical results are compared with analytical solutions. The present results are obtained with fairly good accuracy.
