Investigating the Effects of Pressure on the Near Tip Behavior and Crack Growth in a Particulate Composite Material
Abstract
The objective of this report is the investigate the effects of confining pressure and loading history on the near tip behavior and crack growth in a particulate composite material. The conclusions are: the crack growth rate under ambient pressure is significantly higher than that under 8697 KPa confining pressure. At the onset of crack growth, the crack opening displacement under 8697 KPA confining pressure is greater than that under ambient pressure. At the onset of crack growth, confining pressure has no significant effect on the size of the high-strain zone. Under constant strain condition, the crack stops growing after it propagates a short distance.
