Abstract
Dynamic stress intensity factor K1D and crack velocity ȧ were determined using single-edge-cracked tensile specimens of PMMA and Homalite-100. To study unloading behavior of the material, load P applied to the specimen was also evaluated as a function of time t. Unloading rate Ṗ, the time derivative of P, was determined to correlate with K1D and ȧ. The findings showed that the change in Ṗ was qualitatively in accord with the change in K1D or ȧ. However, there existed slight differences among the values of t giving peak values of Ṗ, K 1D and ȧ, so that their order was ȧ, Ṗ and K 1d.
