Experimental and numerical analysis of micromechanical damage in the punching process for High-Strength Low-Alloy steels [PDF]

open access: yes, 2014
Sequential sheet metal forming processes can result in the accumulation of work hardening and damage effects in the workpiece material. The mechanical strength of the final component depends on the “evolution” of these two characteristics in the ...

Research progress on the micro-mechanism and prediction models of ductile fracture in metal forming

open access: yes工程科学学报, 2018
Metals with a high strength-to-weight ratio are being increasingly used in the automobile industry to achieve a reasonable tradeoff between weight reduction, crashworthiness, fuel efficiency, and environmental friendliness. However, sheets of lightweight

Plasticity and Ductile Fracture of High-Strength Steel Center-Holed Plates under Tension

open access: yesMetals, 2023
The mechanical behavior of bolted connections in high-strength (HS) steel structures is a matter of concern, since the less ductility compared to mild steels may affect the load transfer and stress distribution of bolted connections.

Effects of graphite nodules on crack growth behaviour of austempered ductile iron [PDF]

open access: yes, 2007
Austempered ductile iron (ADI) is a candidate material for camshafts, where however, the early stages of fatigue damage are of major concern during service.

On continuum models of ductile fracture [PDF]

open access: yesJournal of Materials Science, 1970
Several fracture criteria are reviewed with respect to ductile fracture. It is suggested that both critical crack-tip displacement, 2Vc*, and critical fracture strain,∃*, criteria may describe the fracture of a ductile second phase rod in a ductile matrix.

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 ...
