Abstract

Equations have been developed to determine the dynamic stress field and strain field around a crack moving at a constant velocity in a finite size orthotropic composite material. A simple experimental technique using strain gages has been used to determine the dynamic stress intensity factor for cracks propagating in a unidirectional glass-epoxy composite laminate. Evaluation of the optimum size, orientation and location of the strain gage to minimize errors has been discussed. © 1994.
