Numerical integration of an advanced Gurson model for shear loading: Application to the blanking process [PDF]

open access: yes, 2013
A new extension of the Gurson damage model has been proposed recently to predict ductile fracture under shear dominated loads. The aim of this work is to verify the ability of this approach to simulate, in an accurate way, the damage evolution in ...

Ductile failure analysis of high strength steel in hot forming based on micromechanical damage model

open access: yesMATEC Web of Conferences, 2016
The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters.

Effect of the Stress State Triaxiality on the Value of Limit Strain of Micro-Void Development in S235JR Steel - Numerical Analysis

open access: yesCommunications, 2011
This paper deals with the numerical analysis of plastic deformation and damage development in S235JR steel in complex stress states. The material Gurson Tvergaard Needleman (GTN) model was applied. The analysis was performed for notched bars subjected to

Parameters Determination of GTN Model and Damage Analysis of Aluminum Alloy 6016 Sheet Metal [PDF]

open access: yesAdvances in Physics Research, 2014
Taking the material of AA6016 (Aluminum Alloy 6016) which is widely used in automobiles as the object of this study, the mechanical properties based on GTN (Gurson-Tvergaard-Needleman) model had been investigated. The parameters of the GTN model which were used for simulation were identified by uni-axial tensile test, parameter fitting and the inverse ...

Effect of allopurinol on phosphocreatine recovery and muscle function in older people with impaired physical function:a randomised controlled trial [PDF]

open access: yes, 2020
Background: Allopurinol has vascular antioxidant effects and participates in purinergic signalling within muscle. We tested whether allopurinol could improve skeletal muscle energetics and physical function in older people with impaired physical ...

Identification of damage and fracture modes in power electronic packaging from experimental micro-shear tests and finite element modeling [PDF]

open access: yes, 2017
Micro-shear tests are performed in order to characterize the mechanical behavior and the fracture of the chip/metallized ceramic substrate assemblies of power electronic devices. These assemblies are elaborated using three types of junctions: AuGe solder/

Review on the damage behavior of metal laminated composite

open access: yesMaterials Research Express, 2020
Metal laminated composite (MLC) have attracted widespread attention for their potential in achieving excellent properties. However, damage and failure are more likely to occur during the plastic deformation due to the existence of the interface region ...

Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.
