One of the attractive low activation steels is the austenitic Mn-Cr steel from the view point of waste disposal because of few long-lived nuclides. In this paper, three types of Mn-Cr austenitic steels were fabricated by vacuum induction furnace. Then plates with 10 mm thickness were fabricated by hot-rolling. The physical metallurgy of these steels was studied by the corrected Schaeffler diagr...

Numerical homogenization is an excellent tool for the quick simplification of complex structures with a model that much simpler and, at same time, accurately reflects mechanical behavior original model. Corrugated cardboard modeling, all geometrical nuances preserved, complicated and time-consuming process. The transfer full 3D corrugated board composed two flat layers middle layer to one only,...

This paper proposes a new type of steel slip-friction column base connections with arc end-plates. Two end-plates the base, which can slide between each other to some extent, were set at position where is subject plastic deformation. Thus, sliding-friction energy dissipation effectively minimize or eliminate traditional connections. Cyclic loading tests conducted study hysteretic performance an...

Explosion load studies are an essential part of shield engineering design. This is especially true for explosion-proof plates, which used in order to reduce the impact explosions, have potential cause substantial damage structural elements. The purpose this study detail explosion phenomenon and response sandwich panel structures under explosive loading. finite element method (FEM) model dynamic...

The molded polystyrene wallboard with steel skeleton is composed of cold-formed thin-walled skeleton, flame-retardant particles a special adhesive. lattice columns battens were tested under axial compression and eccentric compression. results show that it reasonable to calculate the ultimate vertical bearing capacity specimen by comparing experimental theoretical calculation results. It found t...
