Identification of Nonlinear Dynamic Behavior and Failure for Riveted Joint Assemblies

open access: yesShock and Vibration, 2000
Many different types of rivets need to be modeled to analyze the crashworthiness of aircraft structures. A numerical procedure based on FE modeling and characterization of material failure constitutive models is proposed herein with the aim of limiting ...

Continuum Damage-Healing Mechanics with Introduction to New Healing Variables [PDF]

open access: yes, 2012
In this study, damage and healing mechanisms are discussed in detail with special emphasis given on two new healing variables. They are introduced in terms of healing variable based on area and healing variable based on elastic stiffness.

Investigation of continuum damage mechanics model without element size sensitivity

open access: yesNihon Kikai Gakkai ronbunshu, 2017
A discontinuous material behavior such as ductile fracture and fatigue failure is predicted actively in various fields by FEM. There is continuum damage mechanics as a method to evaluate the discontinuous material behavior in a framework of continuum ...

A Modified Fatigue Damage Model for High-Cycle Fatigue Life Prediction

open access: yesAdvances in Materials Science and Engineering, 2016
Based on the assumption of quasibrittle failure under high-cycle fatigue for the metal material, the damage constitutive equation and the modified damage evolution equation are obtained with continuum damage mechanics.

Combining damage and fracture mechanics to model calving [PDF]

open access: yesThe Cryosphere, 2014
Calving of icebergs is a major negative component of polar ice-sheet mass balance. Here we present a new calving model relying on both continuum damage mechanics and linear elastic fracture mechanics.

Modelling of Dynamic Behaviour of Orthotropic Metals Including Damage and Failure [PDF]

open access: yes, 2012
A physically based material model for metals, with elastic plastic and damage/failure orthotropy is proposed in this paper. The model is defined within the frameworks of irreversible thermodynamics and configurational continuum mechanics and integrated ...

A continuum damage mechanics-based approach for the high cycle fatigue behavior of metallic polycrystals [PDF]

open access: yes, 2018
International audiencePolycrystalline elasto-plasticity models provide a general framework for investigating the effect of microstructural heterogeneities (e.g. grains, inclusions, pores) on the high cycle fatigue behavior of metallic materials.

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept

open access: yesJournal of Applied and Computational Mechanics, 2015
Springback is one of the most common and important issues in metal forming area. Due to it depends on variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) based on the Lemaitre isotropic ...
