This paper deals with the multi-pulse chaotic dynamics of a sandwich plate with truss core under transverse and in-plane excitations. In order to analyze the complicated nonlinear behaviors of the sandwich plate model by means of the improved extended Melnikov technique. the two-degrees non-autonomous system is transformed into an appropriate form. Through theoretical analysis. https://www.wholisticpet.shop/product-category/canine-grooming-bathing-products-shampoo/
