The aim of this study is to investigate stress wave propagation in metal foams under high-speed impact loading. Three-dimensional Voronoi model is established to represent real closed-cell foam. Based on the one-dimensional stress wave theory and Voronoi model. a numerical model is developed to calculate the velocity of elastic wave and shock wave in metal foam. https://www.bekindtopets.com/mega-choice-Nutri-Vet-Uri-Ease-Paw-Gel-for-Cats-hot-buy/
