Application of damage mechanics in percussive drilling modelling [PDF]

open access: yes, 2005
A stationary-periodic quasi-static model of rock percussive deep drilling is introduced. First, an auxiliary problem of stationary indentation of a rigid indentor is considered.

Research Review on the Damage Theoretical Model of Metal Materials

open access: yesTaiyuan Ligong Daxue xuebao, 2023
The plastic deformation of metal material is accompanied by surface defects, internal defects, damage cracks, etc., and these defects seriously restrict the processing of metal and its performance improvement.

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 ...

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.
