P-version of finite elements for the analysis of stress concentrators

We study the applicability of thep-version of the method of finite elements to the numerical analysis of the concentration of stresses near notches by using a COSMOS/M computer system and the Stress-Check software package. We present the numerical analysis of the stress-strain state of the material near notches of various shapes. The efficiency of the proposed procedure of numerical computations is demonstrated by computing the nominal and plastic stress concentration factors for beam and cylindrical specimens with notches.
