Fatigue Crack Growth in High Polymeric Solids

抄録

The effects of stress ratio, environment, frequency and temperature on the rate of fatigue crack growth are investigated by use of polycarbonate, polymethyl methacrylate, polyvinyl chloride and ABS resin. It is found that the crack growth rate can be expressed by a power law of the range of stress intensity factors and the constants of the law are strongly influenced by the factors mentioned above. And an empirical relation taking those factors into account is proposed.
