Accurate predictions of thin sheet material springback during forming processes are great interest in the industry. However, sheets susceptible to buckling under shear loading. The present research aims at improving so-called Arcan setup for testing (1-5 mm) samples with large gauge areas (i.e., width about 21 by introducing anti-buckling devices mitigate sample buckling. Three monotonic and on...

Tube spinning is an effective plastic-forming technology for forming light-weight, high-precision and high-reliability components in high-tech fields, such as aviation and aerospace. However, cracks commonly occur in tube spinning due to the complexity of stress state, which severely restricts the improvement of the forming quality and forming limit of components. In this study, a finite elemen...

During the development of an automobile part obtained by stamping process, time and money are required aiming process planning setup a new tooling. One difficulties in is to know if chosen material will have sufficient formability reach final form project. Because this difficulty, it very interesting propose method that can accurately simulate forming process. The failure criteria be mathematic...

The use of high strength steel (HSS) cold-formed hollow section is significant interest in the construction sector due to competitive costs. accurate simulation ductile fracture failure at micro and macro scale critical for improving validity predicting structural behaviour HSS sections welded joints. In this study, S700 material studied using Gurson-Tvergaard-Needleman (GTN) damage model. Repr...

It is known that nuclear deformation plays an important role in inducing the halo structure neutron-rich nuclei by mixing several angular momentum components. While previous theoretical studies on this problem literature assume axially symmetric deformation, we here consider non-axially deformations. With triaxial $\Omega$ quantum number admixed a single-particle wave function, where projection...

The morphology of haloes inform about both cosmological and galaxy formation models. We use the Minkowski Functionals (MFs) to characterize actual haloes, only partially captured by smooth density profile, going beyond spherical or ellipsoidal symmetry. employ semi-analytical with NFW $\alpha\beta\gamma$-profile shape obtain a clear interpretation MFs as function inner outer slope, concentratio...

Multi-layered plates consisting of DH-36 steel coated by a thick layer of polyurea, for increased blast and impact protection, are of increasing importance to the Department of Defense. A hybrid approach of experiments and simulation was performed to characterize fracture and plasticity of DH-36 Navy steel, which is the first step in creating an accurate model of the composite material. The per...

We develop a multiscale model of ductile damage by void growth in general materials undergoing arbitrary deformations. The model is formulated in the spirit of multiscale finite element methods (FE), that is, the macroscopic behavior of the material is obtained by a simultaneous numerical evaluation of the response of a representative volume element. The representative microscopic model conside...
