Blast-plastic analysis was carried out for the corner region of a slit under compressive stress. From this analysis the ratio of work hardening coefficient H' to elastic modulus E play an important role in transition from the elastic stress field to the plastic stress field.
The aspect ratio d/a of a slit under the elast-plast condition affects little the stress concentration at the slit corner. But stress apart from the corner decreases rapidly when the aspect ratio decreases.
