Dynamic compression of square honeycomb structures during underwater impulsive loading

Dynamic Compression of Square Tube Cellular Structures

Aluminum cellular structures have been fabricated by combining a two-dimensional [0◦/90◦]2 arrangement of square Al 6061-T6 alloy tubes with orthogonal tubes inserted in the out-of-plane direction. By varying the tube wall thickness, the resulting three-dimensional cellular structures had relative densities between 11 and 43%. The dynamic compressive response of the three-dimensional cellular s...

Approximate Dynamic Analysis of Structures for Earthquake Loading Using FWT

Approximate dynamic analysis of structures is achieved by fast wavelet transform (FWT). The loads are considered as time history earthquake loads. To reduce the computational work, FWT is used by which the number of points in the earthquake record are reduced. For this purpose, the theory of wavelets together with filter banks are used. The low and high pass filters are used for the decompositi...

Computational Modelling of Concrete Structures Subjected to High Impulsive Loading

Biomechanical Dynamics of Cranial Sutures during Simulated Impulsive Loading

Background. Cranial sutures are deformable joints between the bones of the skull, bridged by collagen fibres. They function to hold the bones of the skull together while allowing for mechanical stress transmission and deformation. Objective. The aim of this study is to investigate how cranial suture morphology, suture material property, and the arrangement of sutural collagen fibres influence t...

Crush dynamics of square honeycomb sandwich cores

Square honeycombs are effective as cores for all-metal sandwich plates in that they combine excellent crushing strength and energy absorption with good stiffness and strength in out-of-plane shear and in-plane stretch. In applications where sandwich plates must absorb significant energy in crushing under intense impulsive loads, dynamic effects play a significant role in the behaviour of the co...
