Identification of constitutive equations at very high strain rates using shock wave produced by laser

R. Seddik et al.

Summary: A method combining experiments and simulations has been developed to characterize the yield stress and strain hardening of several metals, including pure aluminum, aluminum alloys, and titanium alloy during Laser Shock Peening. The experiments were simulated using three material constitutive equations to identify the material parameters of the Johnson-Cook law by comparing experimental and calculated velocity profiles of the rear-free surface. Results are presented and discussed.

Modeling of multi-edge effects in the case of laser shock loadings applied on thin foils: Application for material characterization of aluminum alloys

M. Ayad et al.

Summary: This article presents a study on the shock wave propagation in aluminum alloys produced by laser plasma. The study uses experimental and numerical tests to analyze the dynamic response of aluminum alloys under high strain rate laser shock. The results show that the 2D compressive effects depend not only on the focal spot size and target thickness, but also on the power density and material initial yield strength.

Numerical investigation of the effect of laser shock peening parameters on the residual stress and deformation response of 7075 aluminum alloy

Y. F. Xiang et al.

Summary: This study investigated the effects of massive laser shot peening on metallic materials using a finite element model, focusing on the impact of scanning patterns, overlapping rates, and spot shapes on residual stress and displacement deformation. The results showed that a better treatment could be achieved with massive square spot impact, snake scanning pattern is an optimized pulse sequence, and increasing overlapping rate improves the uniformity of compressive residual stress field.

Summary: The method proposed in this study utilizes Fast Fourier Transform to obtain the dispersion relation of acoustic waves in heterogeneous periodic media with arbitrary microstructures. By solving an eigenvalue problem for Bloch waves in Fourier space, the method effectively combines the simplicity of classical Fourier series analysis with the versatility of Finite Elements.

Reconstruction of heterogeneous surface residual-stresses in metallic materials from X-ray diffraction measurements

Leo Morin et al.

Summary: This paper aims to provide spatially resolved distributions of residual stresses using X-ray diffraction measurements and a spatial deconvolution technique. The method is first applied to reconstruct residual stresses in two reference cases with strong agreement between the reference stress profiles and the reconstructed ones. Experimental X-ray diffraction measurements also show a good agreement between the local stress profile reconstructed from the measurements and that predicted numerically.
