Abstract In general, a large part of the time is devoted to design and production reliable parts where extensive knowledge required for engineers come up with an optimal solution tooling sheet metal forming processes. Most time, principle trial error used get desired shapes products. This because prediction deformations occurring in elements not available highly dependent on geometry part, tool...

The deflection and fracture of metal sandwich plates subjected to intense uniform impulsive pressure loads are studied for plates made of four steels representing a wide range of strength, strain hardening and ductility. Sandwich plates with both square honeycomb cores and folded plate cores are considered. The primary fracture modes of the sandwich plates are necking and subsequent tearing of ...

Hindu Kush subduction zone produces large intermediate-depth earthquakes within a small volume every 10–15 years. Here we study the last three M ≥ 7 events within the cluster and find complex and diverse rupture processes. However, their main subevents appear to recur on the same fault patch, dipping 70° to the south. This recurrence requires an average of 9.6 cm/yr slip rate on the patch, much...

Molecular dynamics (MD) simulation was performed on an fcc solid platinum nanowire in this study. Infinite one-dimensional nanowires of circular and rectilinear cross sectional shapes were subjected to uniaxial tensile strain, and simulated at temperatures of 50K and 300K. The constitutive stress-strain response of the nanowire was investigated, the changes in crystal structure during axial def...

Lithospheric extension can generate passive margins that bound oceans worldwide. Detailed geological and geophysical studies in present and fossil passive margins have highlighted the complexity of their architecture and their multi-stage deformation history. Previous modeling studies have shown the significant impact of coarse mechanical layering of the lithosphere (2 to 4 layer crust and mant...

The effects of solution treatment time on the morphology evolution Si particles and thermal conductivity tensile properties Sb-modified alloys were studied. results show that follows four mechanisms: spheroidization, necking splitting with large aspect ratios, fusion spherical particles, coarsening controlled by diffusion. first three mechanisms mainly occur at early stage treatment. addition S...
