Computational tools for the fatigue life modeling and prediction of composite materials and structures

2019
Book Chapters

Abstract

Structural testing is probably the best and only way to reveal the actual performance of composite laminates, structural components, and complete composite structures under fatigue loading. Nevertheless, the high cost, and the multitude of loading cases a composite structure can face during operation, hinder the possibility of developing methods based solely on experimental results and therefore, theoretical modeling procedures become essential. The complexity of the calculations and model execution for the application of such methods constitutes the implementation of the necessary steps in computer programs indispensable. This chapter presents a state of the art of the existing computational tools for fatigue assessment of composite materials and structures.

Composite material

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.

Structural analysis

Structural analysis is a branch of solid mechanics which uses simplified models for solids like bars, beams and shells for engineering decision making. Its main objective is to determine the effect of loads on the physical structures and their components. In contrast to theory of elasticity, the models used in structure analysis are often differential equations in one spatial variable. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, aircraft and ships.

Structural load

A structural load or structural action is a force, deformation, or acceleration applied to structural elements. A load causes stress, deformation, and displacement in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements. Excess load may cause structural failure, so this should be considered and controlled during the design of a structure. Particular mechanical structures—such as aircraft, satellites, rockets, space stations, ships, and submarines—are subject to their own particular structural loads and actions.
