Modeling of Residual Stresses in Thin Metal Films
Residual mechanical stresses introduced during deposition of thin films and coatings have a significant impact on the reliability of electronic devices and structural components. The mechanical stress in thin metal films consists of a thermal component and an intrinsic component due to the evolution of the metal microstructure during film growth. Controlling of the intrinsic stress component ha...
متن کاملSurface Workhardening and Residual Stresses Induced by Micro Cutting Processes
X-ray diffraction, optical microscopy and microhardness testing have been used to study properties which develop in micro-cut AISI 1045 steel. The influence of the ploughing effect on residual stresses, surface deformation and work hardening, and the tool quality were investigated. Tensile residual stresses, caused by the heat generated in the material during the cutting process, were observed ...
متن کاملAn Analytical Model for Shot-Peening Induced Residual Stresses
To improve the fatigue life of metallic components, especially in aerospace industry, shot peening is widely used. There is a demand for the advancement of numerical algorithms and methodologies for the estimation of residual stresses due to shot peening. This paper describes an analytical model to simulate the shot peening process and to estimate the residual stress field in the surface layer....
متن کاملResidual Stresses Measurement of a Quenched Cylinder using Slitting Method
Residual Stress measurement has gained interests among researchers for many years due to its great influence on the structural integrity. Slitting method is one of the destructive techniques that relies on the introduction of an increasing cut to a part containing residual stresses. Similar to all other mechanical strain relief techniques, slitting also suffers from its shortcomings during the ...
متن کاملBACK STRESSES IN CREEP OF 2024Al-SAFFIL FIBRE COMPOSITE
INTRODUCTION The aim of the present paper is to compare creep behaviour of aluminium-based alloy (2024AA) prepared by an identical technology with and without reinforcement by short alumina fibres and with two different orientations of fibres. The observed behaviour is analyzed in terms of back stresses obtained by threshold stress approach from steady-state data or by the internal stress appro...
