Near Tip Behavior in a Particulate Composite Material Under Constant Strain Rates Including Temperature and Thickness Effects

Abstract

The objectives of this report were to investigate the effects of temperature and specimen thickness on local strain fields and crack growth behavior in a particulate composite material. Temperatures were -53.9 deg C, 22.2 deg C and 73.9 deg C. Thickness is 2.54 mm and 12.7 mm. The conclusions were that the crack growth behavior at -53.9 deg C is significantly different from that at 22.2 deg C and 73.9 deg C. The increase in specimen thickness alters the local strain fields but the iso-strain contours are of the same general form. A power law relationship exists between the Model stress intensity factor and the crack growth rate.
