Abstract
: The main of this study is yo presents a prediction of creep behavior beam with opening crack at 45° subjected to a constant load during 12hours (720mn) and describe a procedure for modeling the primary creep law using ANSYS ® software. The procedure modeling of creep behavior consist to applied the finite element method (FEM) based on a model called (Modified Time hardening model) using the computer code ANSYS 17.1. This paper illustrates a new approach of study crack and creep behavior by the FEM in the elements structural. Crack analysis is typically accomplished using either the energy criterion or the stress-intensity-factor criterion. For the energy criterion, the energy required for a unit extension of the crack (the energy-release rate) characterizes the fracture toughness. For the stress-intensity-factor criterion, the critical value of the amplitude of the stress and deformation fields characterizes the fracture toughness. ANSYS ® 17.1 software has been used to perform the numerical calculation in this paper. The main objective of this study is to determine the distribution of stresses, creep strains as well as the mechanical behavior around crack. Results show that creep strain rate, and the resulting axial stresses will gradually increase at the spring line of the final lining.
