摘要：

Assuming that a material point becomes unstable when the effective plastic strain there reaches a critical value, it is found that a material instability will initiate at a point on the crack-tip of an impulsively loaded prenotched plate that makes an angle of -14 degrees to the notch-tip. This agrees well with the observed values of -5 degrees to -15 degrees. (C) 1998 Elsevier Science Ltd. All rights reserved.
