We did an experimental study to investigate the effect of the thermal stress due to the heater for adjusting adaptive flying height (AFH) on the readability and instability of tunneling magnetoresistance (TMR) sensors. The slider head consists of a small heater nearby the read/write elements for controlling the clearance between the read/write elements and the recording medium of the magnetic r...

the effects of physical, thermal and mechanical parameters on curing microthermal residual stresses are studied, based on the energy method, to present a theoretical solution for prediction of residual stress felds. a fnite element analysis is developed to compare the theoretical and numerical results together. there is found to be a good agreement between the results of the two methods. howeve...

In the present study, stress analysis and explicit solution of rectangular plate with arbitrarily located circular hole, subjected to linear normal stresses on two opposite edges, has been investigated. Airy function and hoop stresses occurring at the edge of the circular have been computed. In this method 2D dimension elasticity and Airy stress function was used. The present method for explici...

In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

This paper presents a family of mixed finite elements on triangular grids for solving the classical Hellinger-Reissner mixed problem of the elasticity equations. In these elements, the matrix-valued stress field is approximated by the full C0-Pk space enriched by (k − 1) H(div) edge bubble functions on each internal edge, while the displacement field by the full discontinuous Pk−1 vector-valued...

A numerical analysis of stresses generated in bending fatigue specimens has been performed employing the commercially available FEM-program ADINA. The results show that transverse bending occurs, giving rise to a stress enhancement in the edge region. A stress maximum is obtained approximately 2 mm away from the specimen edge. This result is consistent with the fact that fatigue initiation pred...

Diamond coatings have been increasingly used in cutting tools applications. Coating delamination is the major tool failure mode and occurs due to deposition-induced residual stresses and thermomechanical loading in machining. This study applies finite element analysis to investigate stress distributions, with the edge radius focused, in diamond coating tools considering depositions and machinin...
