Temperature Dependence of Stress Concentration Factors in Composite Materials.

Abstract

This thesis reports the results of an experimental investigation of the effects of temperature on the strain concentration factor due to a circular hole in a graphite/epoxy laminated composite plate subjected to tension in a principal material direction. It is shown that for the (0/+ or - 45 deg/0)s laminate tested, the strain concentration factor at 300 degrees Fahrenheit was 20% greater than the room temperature value. This variation is not predicted by classical solutions based on homogeneous orthotropic elasticity. (Author)
