Abstract:Abstract. This paper aims to analyze the plastic collapse moment of circumferential cracked cylinder under pure torsion using the NSC approach and 3D FE model. The material considered in this work is assumed to be elastic-perfectly plastic. The influences of geometric parameters of crack and cylinder, such as � ⁄ , ⁄ and ⁄ on solution of plastic collapse load are also investigated. The analysis shows that for the case of ⁄ < 0.75, the values of limit torsion moment can be estimated by NSC analysis which provid… Show more
