Ratcheting behavior of steel 304L cylindrical shell under cyclic combined and axial loading are investigated in this paper, numerically. Cylindrical shells were fixed oblique at angle of 20° and normal with respect to the longitudinal direction of the shell and subjected to force-controlled cycling with non-zero mean force, which causes the accumulation of plastic deformation or ratcheting beha...

BACKGROUND We compared different plates in an experimental calcaneal fracture model under biocompatible loading. METHODS Four plates were tested: a plate without locked screws (Synthes), and three different plates with locked screws (Newdeal, Darco, Synthes). Synthetic calcanei (Sawbone) were osteotomized to create a fracture model, and the plates were fixed onto them. Seven specimens for eac...

In order to investigate the effect of gas cutting during removal restraining jig on deformation after submerged arc welding, authors have conducted experiments a series processes using constraint plates in test specimen modeling deck steel bridge. this paper, an Idealized explicit FEM developed by is applied detail factors that cause springback plates. A welding and were modeled, then three-dim...

We present the results of our numerical simulation of the dynamic response and deformation of 1 m diameter circular DH-36 steel plates and DH-36 steel-polyurea bilayers, subjected to blast-like loads. Different thicknesses of the polyurea are considered and the effect of polyurea thickness on the performance of steel plates under blast loads is investigated. For each polyurea thickness, we have...

In this study, free vibration of functionally graded rectangular plates for various types of boundary conditions has been presented . The properties of the plate are assumed as power- law form along the thickness direction , while poisson's ratio is kept constant. the linear vibration equations of functionally graded rectangular plates are derived based on first order shear deformation theory b...

This paper extends the previous work of authors and presents a non-layered Finite Volume formulation for the elasto-plastic analysis of Mindlin-Reissner plates. The incremental algorithm of the elasto-plastic solution procedure is shown in detail. The performance of the formulation is examined by analyzing of plates with different boundary conditions and loading types. The results are illustrat...

To explain the mechanics of perforation of thick metallic target plates a modified version of the analysis suggested by Awerbuch and Bodner [2] is given by a cylindrical projectile. Although the analysis retains the basic concept of the perforation process to occur in three stages as was assumed by Awerbuch and Bodner [2] a new explanation, as to the cause and effect of the compressive force is...
