Modal Responses of Mechanical Structures Under Thermo-mechanical Loads Cranfield University

Overview

This Modal Responses of Mechanical Structures Under Thermo-mechanical Loads programme offered by Cranfield University investigates the relationship between dissipated strain energy and changes in the modal response of mechanical structures subjected to thermo-mechanical loading. The research addresses the need for a deeper understanding of how crack propagation influences modal values when cyclic thermal loading is combined with dynamic excitation, reflecting conditions commonly experienced by engineering components and structures.

Key Facts

The project involves the development of an empirical test setup using a modal exciter and a cartridge or induction heating system to apply simultaneous thermal and dynamic loading. Accelerometers, acoustic sensors, and data acquisition systems will be used to measure modal responses and dissipated strain energy under predefined boundary conditions. The resulting measurements will be analysed to establish links between subsurface fatigue development and structural response. Work will be conducted within the Through-life Engineering Services (TES) Centre, which specialises in condition monitoring, damage tolerance, and asset management.
