In this research in numerical analysis software packages SIGMA / W based on the finite element method was to have been used. For this purpose, during the construction of the dam Kaboodval using behavioral models elastic - plastic and elastic non-homogeneous, non-linear elastic, linear elastic been analyzed and pore pressure, stresses in the body and its meeting with the Data Tools the compariso...

Metallic shear panel dampers (SPDs) have been widely adopted in seismic engineering. In this study, axial and torsional specimens of four types of metallic damping materials, including three conventional metallic steels as well as low yield strength steel 160 (LYS160), were tested in order to investigate the material response under repeated large plastic strain and low cycle fatigue between 10 ...

Abstract. The mechanical and damage behavior of a X100 steel after prestrain is studied in this work. Experimental results show both a plastic and rupture anisotropy: the T direction exhibits a higher ultimate stress but the lowest ductility and toughness. Prestrain reduces ductility and crack growth resistance. A model able to represent the plastic and damage behaviour of the material before a...

A detailed analysis is performed of the plastic deformation in a metal substrate fretted by a ̄atbottomed circular peg under steady normal load and cyclic tangential load. The substrate is coated with a thin layer of soft metal. Two limiting asymptotic problems are identi®ed which characterize small scale yielding behavior in the substrate in the vicinity of the corners of the peg. Deformation ...
