Abstract

Purpose

–

To provide more convenient tools for the investigation of real objects with different forms and positions of cracks, which requires fracture analysis of engineering structures.

Design/methodology/approach

–

A method which uses the Trefftz‐type finite elements (T‐elements) was applied as an efficient tool to deal with various problems of fracture mechanics.

Findings

–

Numerical examples compare the results of the T‐element procedures with the commercial systems ALGOR® and ANSYS®, showing the advantages of using the former codes. Their effectiveness is especially visible in the solution of a crack propagation problem.

Research limitations/implications

–

Limitation to linear fracture mechanics.

Practical implications

–

A proposal of effective codes for engineering analysis of structures with cracks.

Originality/value

–

This paper presents the feasibility of the application of the T‐element method to a wider field of fracture analysis – crack propagation in engineering structures.
