In order to meet the increasing requirements of automotive industry for material strength grades and performance, application advanced highstrength steel panels, represented by dual-phase steel, in lightweight vehicle bodies is increasing. Resistance spot welding main joining process body manufacturing. How improve tensile fatigue performance resistance joints great significance structure body....

We investigate the predictive performance of specific analytical and numerical methods to determine effective magnetic properties two-phase steels at macroscale. utilize various mixture rules reported in literature for former, some which correspond rigorous bounds, e.g., Voigt (arithmetic) Reuss (harmonic) averages. For latter, we employ asymptotic homogenization together with finite element me...

Pressure-assisted single-point incremental forming (PA-SPIF) is one of the emerging techniques for sheet metals that have been subject rigorous research over past two decades. Understanding its mechanisms and capabilities growing as a result. Open gaps are still present in material constitutive modelling accurate numerical predictions finite-element simulations characteristics localised deforma...

The influence of pre-strain on the tensile and fatigue properties a dual phase DP600 steel was studied. material pre-strained by uni-axial tension in rolling transverse direction. Thereafter, specimens were cut from deformed plates parallel or orthogonal to It found that increases yield strength. Results suggested strain path change primarily affects elastic-plastic transition during early stag...

This work aims to evaluate the use of miniaturized tensile specimen (MTS) characterise mechanical properties alloys developed through rapid alloy prototyping (RAP), where high throughput tests are required on relatively small amounts material. Tensile were conducted at a variety strain rates and with increasingly smaller sizes, ranging from larger specimens conforming ASTM/ISO standards, down n...

• A calibrated, stress-state based SPR process FE model is developed. The joining feasibility and joint quality of a wide range riveted connections investigated. High rivet leg inner radius values are shown to increase the quality. Low central tip depths relate high probabilities successful formation. Machine learning techniques can classify for riveting scenarios. Developing robust numerical s...
