Comparison of Hydrostatic Extrusion between Pressure-Load and Displacement-Load Models

Differentiating between Load and Displacement Controlled Wear Testing in an Artificial Cervical Disc - A Computational Comparison

Computational Comparison +Bhattacharya, S; Goel V.K; Greenwald A.S +Orthopaedic Research Laboratories, Cleveland, OH, University of Toledo, Toledo, OH [email protected] INTRODUCTION: Osteolysis associated with polyethylene wear has been identified as an important clinical issue with joint arthroplasties [1]. Bench top simulations have emerged as a powerful preclinical tool to predict the we...

load displacement behavior of concrete beam under monotonic static and low velocity impact load

experiments were carried out to observe the influence of loading type on concrete beam specimens. beam specimens made of similar concrete mixture with the same geometry were tested under three point static loading and low velocity drop weight impact loading. load – displacement behavior, absorbed energy dissipation capacity, stiffnesses, failure modes of beam specimens were obtained and discuss...

Experimental and Finite Element Analyses of the Hydrostatic Cyclic Expansion Extrusion (HCEE) Process with Back-Pressure

It is generally known that severe plastic deformation processes with back pressure not only apply higher hydrostatic stress and more deformation compared to what a regular process can apply to a workpiece but also prevent surface defects in the workpiece during the process. Hydrostatic cyclic expansion extrusion (HCEE) was developed recently for processing long ultrafine-grained metals and allo...

Load-displacement behavior of sacroiliac joints.

We measured the load-displacement behavior of both single and paired sacroiliac (SI) joints in fresh cadaver specimens obtained from eight adults between the ages of 59 and 74 years. With both ilia fixed, static test loads were applied to the center of the sacrum along and about axes parallel and normal to the superior SI endplate. Test forces up to 294 N were applied in the superior, inferior,...
