Thermomechanical Fatigue Life Prediction of Notched

Prediction of Fatigue Life in Notched Specimens Using Multiaxial Fatigue Criteria

In this research, the effects of notch shape on the fatigue strength of 2024-T3 aluminum alloy notched specimens have been studied using experimental and multiaxial fatigue analysis. For this purpose, four set of specimens with different notch shape were prepared and then fatigue tests were carried out at various cyclic longitudinal load levels. Load controlled fatigue tests of mentioned specim...

Physically-based Finite Element Strength Prediction in Notched Woven Laminates under Quasi-static Loading

The present paper is concerned with modelling damage and fracture in notched woven fabric composites. Previous experimental work has shown that, under tensile loading, damage at a notch in a variety of GFRP and CFRP composites based on woven fabric reinforcement comprises matrix damage and fibre tow fracture along the plane of maximum stress. It is these experimental observations that inform th...

Stress-strength reliability models under incomplete information

A new approach to compute structural reliability is proposed. The novelty of the approach is that initial statistical information concerning the stress and strength of engineered structures is partial. Different numerous cases of state of knowledge about the stress and strength are analysed. A set of canonical analytical expressions for computing imprecise structural reliability has been obtain...
