In this research, first DIN1623 St12 steel is selected because of its remarkable formability
and wide application in metal forming industries. As the main contribution and objective of …

Abstract St14 steel (DIN 1623) is widely used in sheet metal forming industries because of
its remarkable formability and also its low price. In this paper, damage behaviour of St14 …

Continuum damage mechanics (CDM) studies the deterioration of mechanical properties in
materials that leads to material failure. The Lemaitre's ductile damage model is known as a …

In this paper, first, an experimental procedure to identify the damage parameters has been
established for A533-B1 alloy steel under stress triaxiality condition. Next, a fully coupled …

This paper aims to present a Continuum Damage Mechanics based fracture model. Two
yield surfaces, plastic and damage, are utilized to develop the model. A modified ductile …

The ductile fracture behaviour of metallic materials is strongly dependent on the material's
stress state and loading history. This paper presents a concept of damage initiation and …

Damage of metals is a progressive physical process which finally leads to the failure of
them. In this study, first, a coupled elastic-plastic-Lemaitre's ductile damage model combined …

Prediction of damage evolution in ductile metals is among the most important challenges
ahead of researchers. Most of damage models are divided into micromechanical and …

In addition to the stress triaxiality, the Lode angle has recently been recognized as an
important parameter influencing the ductile crack initiation, propagation and final failure of …
