Numerical simulation of sheet metal forming processes has become indispensable in the last decades. Although complexity frictional behaviour is identified as a key factor for prediction accuracy, industry commonly considers constant friction coefficient whole tool. Furthermore, influence roughness distribution tool not yet been addressed. In this study die local an advanced model evaluated three industrial automotive components. The newly implemented (TriboZone) suggested advance or mature...
As important light-weight structure material, aluminum alloys have been widely used in automotive and aerospace industries. In the last years, manufacturing of parts with high strength good dimensional accuracy has become main objective industrial applications. Within available alloys, 7xxx series attract interest designers due to yield ultimate tensile they present. However, formability these as-received condition is very poor at room temperature various studies are being carried out...
In this work the formability of a high strength aluminium alloy (AA7075-T6) for stamping an automotive component has been studied. Due to low selected alloy, two different heat assisted forming strategies have analysed. On one hand, W-temper process, where thermal process is carried out prior operation. other hot at same time as forming. The results showed that both technology were able form avoiding any failure material. contrary, processes reduced final mechanical properties material...
High entropy alloys, characterized by their near-equimolar compositions of five or more elements, exhibit unique properties including high strength, thermal stability, and corrosion resistance, making them ideal candidates for demanding applications. Unfortunately, experimental research on behavior under processing in-use conditions is expensive time-consuming. Therefore, the use computer-aided technology design required. However, reliable constitutive material models these alloys are rarely...
The increasing demands for lightweight design in the transport industry have led to an extensive use of materials such as aluminium alloys. forming sheets however presents significant challenges due low formability and increased susceptibility galling. tailored workpieces controlled die roughness surfaces are common strategies improve tribological behaviour, whilst galling is still not well understood. This work aimed at analysing interplay between sheet tool surface on friction performance....
Modeling the elastic behavior of dual-phase steels is complex due to strain dependency Young's modulus and high nonlinearity. Since it assumed that reasons for this are be found in microstructural behavior, microscopic in-situ analysis necessary, but overlap martensite ferrite peaks, evaluation diffraction profiles highly complex. Within work, CR590Y980T (DP1000) investigated a continuous cyclic tensile tension-compression test under synchrotron radiation at High Energy Material Science...
Roll levelling is a forming process used to remove the residual stresses and imperfections of metal strips by means plastic deformations. During fibres are subjected cyclic tension-compression deformations leading achieve flat product. The especially important avoid final geometrical errors when coils cold formed or thick plates cut laser. In last years, due appearance high strength materials such as Ultra High Strength Steels, machine design engineers demanding reliable tool for...
Abstract During the forming and manufacturing of engineering materials, plasticity behavior could be evolving significantly due to complex deformation history. Therefore, this study aims characterize evolution an aluminum-magnesium alloy under simple monotonic non-monotonic loading with abrupt strain path changes. Instead focusing only on one single stress state in first-step for most studies literature, current testing program investigates three states – uniaxial, plane-strain, biaxial...
The effect of the anisotropy, loading rate and stress state on ductile fracture AA5754 cold-rolled sheets has been investigated. plasticity analysed experimentally testing biaxial uniaxial tensile specimens machined at several orientations with respect to rolling direction calibrating Yld2000-3D yield criterion. strain dependency material evaluated notched tension different rates. resulting force–displacement curves, showing negative sensitivity, have employed identify work hardening...
