An etching based axisymmetric solution for the determination of residual stresses in long fibre reinforced metal matrix composites
This paper presents a new inverse axisymmetric model that uses the fibre deformation obtained when the matrix is selectively etched away in order to back calculate the inherent residual stresses. The model is tested using simulation and experimental data. The new solution obviates the ambiguity in an existing solution and is more accurate.
The work builds on analysis carried out with Oxford Instruments on the determination of residual stresses in superconducting magnet coil wires. The work also benefited from collaboration with a colleague at the Open University with expertise in optical and moiré measurement of small deformations and strains.
