Evaluation of the Fracture Parameters for SA - 516 Grade 70 Material
نویسنده
چکیده
Pressure vessels are used in variety of industries like petroleum refining, oil and gas, chemical, power, fertilizers etc. In this paper the rupture phenomenon occurring in the ductile failure has been studied using the Fracture Mechanics approach. The material selected for this study is the low carbon steel (SA-516 Grade 70) widely used for making pressure vessels. Compact Tension (C(T)) specimens of 9.6 mm thickness made of the carbon steel SA-516 Grade 70 are investigated for the fracture toughness. Stress Intensity factor (K), Energy release rate (G) and J-Integral are some of the parameters for the fracture study, which are determined in this work for the chosen material. The aim of the work is to study and predict the fracture strengths of the selected material.

متن کاملModelling of Crack Growth Using a New Fracture Criteria Based Peridynamics
Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation. On the other hand, a new fracture criterion based on the crack opening displacement combined with peridynamic (PD-COD) is proposed. When the relati...
متن کاملEvaluation of Fracture Parameters by Coupling the Edge-Based Smoothed Finite Element Method and the Scaled Boundary Finite Element Method
This paper presents a technique to evaluate the fracture parameters by combining the edge based smoothed finite element method (ESFEM) and the scaled boundary finite element method (SBFEM). A semi-analytical solution is sought in the region close to the vicinity of the crack tip using the SBFEM, whilst, the ESFEM is used for the rest of the domain. As both methods satisfy the partition of unity...
