Simple Determination of Creep Limit for Mild Steel

Numerical Determination of the Forming Limit Diagram for 304 Stainless Steel Based on Phase Change in Deep Drawing Process

Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...

Lecture 14 : Creep – Resistant Steel , Case Study

Introduction Typical operating parameters for steels used in the manufacture of power plant are compared against corresponding values for nickel alloys in aeroengines, in Table 1. In both cases, the service conditions are severe. But this is especially so for steels where the service life is many decades. The degree of reliability demanded of heat resistant steels is therefore extraordinary, an...

The Unified Creep-Fatigue Equation for Stainless Steel 316

Background—The creep-fatigue properties of stainless steel 316 are of interest because of the wide use of this material in demanding service environments, such as the nuclear industry. Need—A number of models exist to describe creep-fatigue behaviours, but they are limited by the need to obtain specialized coefficients from a large number of experiments, which are time-consuming and expensive. ...
