Impact resistance of 304L type stainless steel plates: Identification of Lemaitre and Chaboche damage model's parameters at different strain rates. Comparison with experimental results

, 2000
The aim of the study is to validate the Lemaitre Chaboche damage model in the explicit finite element code EUROPLEXUS. Tensile tests have been performed on smooth and notched specimens of 304L type stainless steel to determine Lemaitre and Chaboche ...

Consistency in Solving the Inverse Problem of the Voce-Chaboche Constitutive Model for Plastic Straining

This paper focuses on an inverse problem involving a commonly used material model in structural steel applications—the Voce-Chaboche model. In particular, the paper proposes an approach focused on obtaining a consistent set of material parameters that ...

Progressive deformation behaviour of thin cylindrical shell under cyclic temperature variation using Combined Hardening Chaboche Model

Latin American Journal of Solids and Structures
This study intends to evaluate thermal ratchetting deformation due to cyclic thermal loading along the axis of a smooth cylindrical shell. Two cases of progressive deformation behaviour are discussed for different loading methods.

Data-driven accelerated parameter identification for Chaboche-type visco-plastic material models to describe the relaxation behavior of copper alloys

691702Background Calibrating material models to experimental measurements is crucial for realistic omputational analysis of components. For complex material models, however, optimization-based identification procedures can become time-consuming ...

Thermomechanical Analysis of PBF-LB/M AlSi7Mg0.6 with Respect to Rate-Dependent Material Behaviour and Damage Effects

Applied Mechanics
This paper describes the self-heating effects resulting from mechanical deformation in the additively manufactured aluminium alloy AlSi7Mg0.6. The material’s self-heating effect results from irreversible changes in the material’s microstructure that are ...

Temperature and plastic strain dependent Chaboche model for 316 L used in simulation of cold pilgering

Cold pilgering is a complex forming process used to produce seamless tubes, posing significant challenges in material modeling due to its non-proportional loading history and extensive accumulated plastic strain. In this study, a temperature- and plastic
