摘要: In the paper short theoretical backgrounds abou t elastic-plastic fracture mechanics were presented and O'Dowd-Shih theory was discussed. Using ADINA System program, values of Q-stress deter mined for vari- ous materials SEN(T) specimen - single edge notched plates in tension presented. The influence kind specimen, crack length material properties (work-hardening exponent yield stres s) on Q-parameter tested. numerical results approximate d by closed form formulas. Presented pap er are com- plementary two papers published 2007 (Gra ba, 2007) 2010 (Graba, 2010), which show describe value SEN(B) CC(T) specimens respectively. mentioned such catalogue value, may be used engineering analy sis calculation real toughness.
