An approximate method for residual stress calculation in functionally graded materials
Thermal residual stresses in functionally graded materials (FGMs) arise primarily from nonlinear spatial variations in the thermal expansion coecient, but can be signi®cantly adjusted by variations in modulus. Thermoelastic analysis of FGMs is complicated by such modulus gradients. A class of problems for which thermal stress solutions for materials with constant modulus can be used as a basis...

متن کاملResidual stress prediction for microelectronic packaging materials
At cure temperatures below Tg the cure shrinkage contributes significantly to residual stress build-up. Residual stresses in a flip chip package The cure shrinkage model was implemented in FE code. In figures 2 and 3 the residual stress build-up for a 2D plane strain model of an adhesively bonded flip chip is shown. A schematic representation of the model is given in the inset of figure 3. For ...
متن کاملNumerical Study of the Effect of Materials’ Plastic Behavior on Equibiaxial Residual Stress Measurement Using Indentation
Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...
متن کاملDisk Vibration Analysis of Functionally Graded Materials
Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus...
