Bone drilling is an essential part of many orthopaedic surgery procedures, including those for internal fixation and for attaching prosthetics. Estimation and control of bone drilling forces are critical to prevent drill breakthrough, excessive heat generation, and mechanical damage to the bone. This paper presents a 3D finite element (FE) model for prediction of thrust forces experienced durin...

In recent years, increasing automotive safety by improving crashworthiness has been a focal point in the industry, employing high-strength steel such as press hardenable (PHS). addition to improved strength of individual parts body vehicle, resistance-spot-welded joints these is highly important obtain safe structure. general, dimensions weld nuggets are regarded one criteria for quality spot-w...

The generalized coupled thermo-viscoelasticity of hollow sphere subjected to thermal symmetric shock load is presented in this paper. To overcome the infinite speed of thermal wave propagation, the Lord-Shulman theory is considered. Two coupled equations, namely, the radial equation of motion and the energy equation of a hollow sphere are obtained in dimensionless form. Resulting equations are ...
