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.inmuebleslasmercedes.com/product-category/oven-mitts/
