Investigate Sub Surface Damage and its Impact on Structural Dynamic Behaviour Cranfield University

Overview

This Investigate Sub Surface Damage and its Impact on Structural Dynamic Behaviour programme offered by Cranfield University examines how subsurface fatigue influences the dynamic characteristics of mechanical structures. The project aims to analytically and numerically model changes in modal responses during crack initiation and growth, with particular attention to the effects of combined thermal cycling and resonance loading. The study addresses the need for further investigation into relationships between dissipated strain energy, fatigue progression, and structural behaviour under realistic operating conditions.

Key Facts

Research activities involve analytical and numerical modelling of structures subjected to different boundary conditions. Cyclic thermal loading is applied alongside resonance excitation to evaluate variations in modal characteristics during damage evolution, with findings compared against existing empirical studies. The project is based within Cranfield's manufacturing and Through-life Engineering Services research environment, which provides expertise in condition monitoring, damage tolerance, and asset management, alongside links to industrial organisations and advanced research facilities.
