The forming limits and failure properties of three distinct advanced high-strength steels
(AHSS) have been investigated under various stress states in tensile tests with optimized …

Ductile fracture in metals is a complex phenomenon caused by the nucleation, growth, and
aggregation of micron-sized voids. Existing theoretical models for fracture use …

In order to accurately describe the fracture behaviour of ductile metals in a wide range of
stress states, based on the mechanism of void nucleation, growth, and coalescence during …

The forming limit of sheets usually corresponds to the strain accumulation before localized
necking and is closely related to the loading state. In the viscous pressure forming (VPF) …

The heterogeneous deformation of polycrystalline metals inherently originates from the
intergranular deformation incompatibility. This paper proposes physical parameters related …

The high strength and light weight of the high strength steel (HSS) make it extensively used.
However, the reduction in ductility often leads to prominent fracture issues. The Q690 steel …

This study primarily aims to develop a robust modelling approach to capture complex
material behavior of CP-Ti, appeared by high anisotropy, differential hardening due to …

In this study, fracture of martensitic steel in hole expansion and stretch bending was
predicted by finite element analysis with shell elements. Various mechanical experiments …
