Abstract Abstract

This review paper presents the latest research focusing on the crack propagation of the structures under complex dynamic loads. The reviewed publications involve the variable methodologies to study the fracture mechanics of structures under the fatigue stress regime. Besides, the paper discusses the fatigue crack growth under different loads. The paper presents the research about the thermo-mechanical fatigue and fracture of the structure with metal, composite and polymer materials. In the end, the potential challenges and the current research gaps are summarised. is revie paper prese ts the latest research focusing on the crack propag tion of the structures nder complex dynamic loads.

1. Introduction 1. Introduction

The structures or components generally operate under complex working conditions in practice compared with the experimental environment. Especially the dynamic thermo-mechanical loads are commonly applied to the structures due to the temperature, and mechanical loads change in working environment, such as the piston when the engine is running and engine blades on an aircraft. Under the complex conditions, thermo-mechanical fatigue becomes a critical problem in the practical industry with cracks’ presence and propagation. The growth of cracks leads to structural failure and fracture, once it propagates over a limit. Therefore, it is significant to study how cracks grow in the structure The structures or components generally operate under complex working conditions in practice compared with the experimental environment.
