TL;DR: In this article, the compressive strengths and dynamic response of corrugated sandwich plates with unfilled and foam-filled sinusoidal plate cores are investigated, and a simplified plastic-string model is developed to analytically predict the large deflection and time responses of the clamped sandwich plates under impulsive loading.

TL;DR: In this paper, the results of microhardness tests showed that the fusion zones (FZ) in both types of joints were relatively soft and the width of the softened zone and the degree of softening with ALW was approximately 1/3 and 3/4 those with non-autogenous laser welding (NLW), respectively, the main reason for the softening was that the alloying elements were more concentrated in the grain boundary but non-uniformly distributed.

TL;DR: In this paper, a laser butt welding of explosion welded Ti/steel bimetallic sheet is performed in this work, and the results showed that cracks usually observed in the transition zone of arc welded joint could be effectively avoided by using laser welding and a copper interlayer.

TL;DR: In this article, the dynamic response of geometrically asymmetric sandwich plates with aluminum hexagonal honeycomb core subjected to blast loading is investigated experimentally and theoretically, and it is shown that the theoretical predictions of the deflection of the center point at the rear face sheet is in good agreement with the experimental results.

TL;DR: In this paper, the impact response of fully clamped slender metal foam core sandwich beams with geometrically asymmetric cross-section struck by a heavy mass at midspan is investigated.
