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

摘要

A series of tensile tests were conducted at a constant cross head speed (2.54 mm/min) and three temperatures (-53.9 deg C, 22.2 deg C, and 73.9 deg C) on edge cracked sheet specimens of two thicknesses (2.54 mm and 12.7 mm). The specimens were made from polybutadiene rubber embedded with hard particles. The effects of temperature and specimen thickness on local behavior and strain fields near the crack tip were investigated and the results are discussed.
