Thermal Flying Height Control

The contact between a touchdown sensor and an asperity on a disk is investigated using finite element analysis. The touchdown sensor is embedded in the area of the thermal protrusion of a thermal flying-height control (TFC) slider. A transient thermo-elastic-plastic finite element contact model is developed to simulate the temperature rise of the touchdown sensor due to frictional heating.

Applied Loading

This paper discusses the behaviour of hollow tubes with axisymmetric internal projections subjected to combined axial and internal pressure loading. Predictions from an extensive elastic and elastic-plastic finite element analysis are presented for a typical geometry and a range of loading combinations, using a simplified bilinear elastic-perfectly plastic material model. The axial loading case, previously analysed, is extended to cover the additional effect of internal pressure. All the predicted stress and strain data are found to depend on the applied loading conditions. The results are normalized with respect to material properties and can therefore be applied to geometrically similar components made from other materials, which can be represented by the same material models.

In this paper ,it analyses the push-extend multi-under-reamed pile in use of elastic-plastic theory by the software ANSYS.It takes four push-extend multi-under-reamed piles which are the same except plates' distance.It introduces the realative theory to make the anlysis much more accuracy.The results which is taken by ANSYS are researched to find out the regularity and can certain the reasonable plate's distance to anlyze the bearing capacity of push-extend multi-under-reamed pile at the same time.
