Over the past few decades, there has been a constant pursuit for lightweight and high-
performance energy absorption structures and materials in automobiles, trains, ships …

A meso-scale modeling approach is used to relate the local microstructural strength and
fracture resistance to the macro-scale failure response of spot welds in hot-stamped ultra …

The VDA238-100 standard for tight radius bending (v-bending) of sheet materials has
received widespread acceptance with automotive suppliers and material producers to …

Thin-walled structures have been widely used as energy-absorbing components, which can
be probably subjected to multiple loading conditions in real life, such as axial crushing and …

The hot stamping of tailored properties is widely established in the automotive industry.
However, unlike conventional press hardening, this technique is designed to generate …

The failure of resistance spot welds in ultra-high-strength press-hardened steels often
occurs due to martensite tempering in the heat-affected zone. In the present work, however …

Three tailored tempering processes without die heating were developed to manufacture
tailored parts having high strength and high ductility zones. In a 1st forming stage, only the …

While adhesive bonding has been shown to be a beneficial technique to join multi-material
automotive bodies-in-white, quantitatively assessing the effect of adherend response on the …

A novel experimental method, dubbed the “Mode I Caiman test”, is introduced to
characterize spot weld failure and propagation within spot weld groups. The test …

Usibor® 1500-AS steel is commonly used in the automotive industry in the die-quenched
form due to its very high level of strength after hot stamping. In order to increase the ductility …
