Contribution to fatigue damage prediction of thin shell finite element models

Abstract

The paper deals with the implementation of the chosen fatigue damage criterions into FE analysis. Our study considers a shell finite element structural analysis in conjunction with the multiaxial rainflow counting and the fatigue damage prediction. The computational analysis considers stochastic response under random excitation in time domain and damage calculation based on so called critical plane approach (CPA).

Finite element method application to calculate the friction discs of the hydromechanical transmission control system

“…In order to solve the problem of prediction of vibration loading of metal-ceramic discs with a high degree of accuracy and to obtain more reliable results it is advisable to use the finite element method [3]. This method is a numerical method for solving differential equations in physics and engineering problems [4][5][6][7].…”

Comparison of the Optical Lock-in Thermography using the Reflection Mode and the Transmission Mode

“…Subsequently, the response is recorded using a thermal camera. Active thermography includes non-destructive testing (NDT) using thermographic systems [1][2][3][4], thermoelastic stress analysis [5][6][7][8][9], methods for assessing the fatigue of materials [10][11][12][13][14][15][16] etc. The bestknown methods in the field of active thermography include:…”
