Journal ArticleDOI
Adiabatic shear instability is not necessary for adhesion in cold spray
Mostafa Hassani-Gangaraj,David Veysset,Victor K. Champagne,Keith A. Nelson,Christopher A. Schuh +4 more
TL;DR: In this article, the authors argue that the large interfacial strain needed to achieve bonding does not necessarily require adiabatic shear instability to trigger, and instead, they suggest that the interaction of strong pressure waves with the free surface at the particle edges can cause hydrodynamic plasticity that effects bonding, without requiring Shear instability, and they proceed on this basis to postulate and confirm a proportionality between critical velocity and the bulk speed of sound.
Journal ArticleDOI
Crashworthiness optimization of corrugated sandwich panels
TL;DR: In this paper, the authors investigated the relationship between structural parameters and the crashworthiness of corrugated sandwich panels under low-velocity local impact and planar impact, and further optimized these structural parameters with the crash-worthiness criteria by using multiobjective optimization techniques.
Journal ArticleDOI
Numerical modeling of ice behavior under high velocity impacts
TL;DR: In this article, a constitutive relation for ice at high strain rates and an algorithm for its numerical integration are developed based on the Drucker-Prager plasticity criteria, which allows a different behavior in tension and in compression.
Journal ArticleDOI
Experimental and numerical research on the low velocity impact behavior of hybrid corrugated core sandwich structures
TL;DR: In this article, a user subroutine VUMAT is developed to model the composite face sheet behavior, in which a progressive damage model based on the Hashin failure criteria and Yeh delamination failure criteria is implemented in ABAQUS/Explicit.

Bird Strike on a Flat Plate: Experiments and Numerical Simulations
Jun Liu,Yulong Li,Xiaosheng Gao +2 more
TL;DR: In this paper, experiments of bird impact with a flat plate are conducted at different striking velocities and simulated using an explicit finite element software PAM-CRASH with three bird material models.

Smoothed particle hydrodynamics: Theory and application to non-spherical stars
R. A. Gingold,Joseph J Monaghan +1 more
Journal ArticleDOI
Smoothed particle hydrodynamics.
TL;DR: In this paper, the theory and application of Smoothed particle hydrodynamics (SPH) since its inception in 1977 are discussed, focusing on the strengths and weaknesses, the analogy with particle dynamics and the numerous areas where SPH has been successfully applied.

Review of Progress in Quantitative Nondestructive Evaluation
TL;DR: The Review of Progress in Quantitative NDE (ROPQN) as mentioned in this paper is the world's leading conference in reporting annually new research and development results in quantitative NDE and promotes communication between the research and engineering communities and emphasize current reporting of work in progress.
Journal ArticleDOI
SPH without a Tensile Instability
TL;DR: In this paper, it is shown how the tensile instability in smoothed particle hydrodynamics can be removed by using an artificial stress which, in the case of fluids, is an artificial pressure.
