Ductile Fracture Analysis of High-strength Steel Bars Using Micromechanical GTN Model [PDF]
Journal of Stress Analysis, 2018 Recent studies on the mechanics of materials have shown that the ductile fracture is significantly affected by the stress invariants among progressive plastic deformation.

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

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

On continuum models of ductile fracture [PDF]
Journal 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.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows
Advanced Engineering Materials, EarlyView.A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

FATIGUE AND TENSILE FRACTURE SURFACE MORPHOLOGIES OF ADDITIVE MANUFACTURED AUSTENITIC STAINLESS STEEL [PDF]
European Journal of Materials Science and Engineering, 2019 Fatigue and tensile fracture surface morphologies of laser additive manufactured (LAM) stainless steel (using powder bed fusion method) were investigated. Both fatigue and tensile fracture surface morphologies were determined using LEO-VP SEM instrument.

Why Ductile Fracture Mechanics? [PDF]
Journal of Engineering Materials and Technology, 1983 Until recently, the engineering application of fracture mechanics has been specific to a description of macroscopic fracture behavior in components and structural parts which remain nominally elastic under loading. While this approach, termed linear elastic fracture mechanics, has been found to be invaluable for the continuum analysis of crack growth ...
