Springback and longitudinal bow are two major shape defects in gradual forming processes like chain-die roll forming. In this study, the springback of AHSS hat U profiles investigated through experiment finite element simulation. The disparity along direction signifies complex deformation during Based on simulation forming, process realized by sequential die blocks causes bending reverse-bendin...

Results: Nickel-titanium wires show exceptional features in terms of elasticity and shape memory effects. However, clinical applications request a deeper knowledge of these properties in order to allow the professional to use them in a rational manner. In addition, the necessary information regarding each alloy often does not correspond to the information given by the manufacturer. Many alloys ...

Abstract The hairpin is a crucial component of the drive motor an electric vehicle, consisting copper coil and very thin enamel layer. It manufactured using successive forming processes due to its complex shape. After processes, springback inevitably observed, which causes critical issues in fabricating motor. Compensating time cost-inefficient process, new process required for cost-efficient p...

Aluminium alloys are one of the most efficient materials for weight reduction in car industry. However, favourable performance conflicts with difficulties transforming these through plastic deformation processes such as stamping. Among different issues, they characterised by a high springback effect. Numerous authors have explored use electro-plastic effect (EPE) to mitigate internal stresses a...

We propose a new penalty, the springback for constructing models to recover an unknown signal from incomplete and inaccurate measurements. Mathematically, penalty is weakly convex function. It bears various theoretical computational advantages of both benchmark $\ell_1$ many its non-convex surrogates that have been well studied in literature. establish exact stable recovery theory model using s...

In real crash cases, simple bending behavior is not common. this case, using the three-point test to examine provides a closer simulation in terms of representation structure under loading. It seen literature that products with tube sections are generally used as door im-pact beams. On other hand, when examining developed high strength steels, it studies on profiles only evaluated hydroforming....
