PHOTOELASTIC STUDIES OF CRACK PROPAGATION AND CRACK ARREST

This report describes the third-year effort on research programs dealing with the characterization of dynamic aspects of fracture. The results included in this report are as follows: (1) verification of BCL one-dimensional computer code; (2) determination of a - K relationship from modified compact - tension specimen; (3) verification of the MRL procedure for K(Ia) measurement with machine-loaded C-DCB specimen; (4) fracture behavior in duplex specimens; (5) crack propagation in a thermally stressed ring specimen; and (6) development of a two-dimensional code.
