Mechanical Shock Analysis and Testing of an Air-Dropped Antarctic Ice Penetrator
… can damage the delicate seismometer. SGIP uses shock isolation to reduce the seismometer's peak acceleration. A structural response model is used to predict the seismometer's dynamic response to ice shelf impacts with hundreds of potential shock isolation designs. This structural response model …

Redesign and shock analysis of HALIFAX class frigate gas turbine uptake structure
… structure is heavily stiffened in order to meet shock resistance requirements. Unfortunately, the result has been that thermal expansion of the uptake shell is constrained, thus every flash-up and shut-down of a gas turbine results in a fatigue cycle of its uptake with extremely high stresses. …

Assessment of LS-DYNA and Underwater Shock Analysis (USA) Tools for Modeling Far-Field Underwater Explosion Effects on Ships
… is modeled with acoustic pressure elements. Analysis of the box barge problem results finds that the program USA is a valid tool for modeling the initial shock response of surface ships when cavitation effects are not considered. LS-DYNA models are found to be very dependent on the accuracy …

Design, testing, and utilization of a spherical shock-recovery system to investigate material response to ultrahigh pressure
The existing shock recovery systems can be classified as planar or convergent. Both systems are used extensively in the study of materials under high pressure. However, a three-dimensional system capable of substantially higher pressure with the capability of full sample recovery would add a new …

Dynamic Analysis of CubeSat Impact on Lunar Surface
… EagleCam. The analyses performed are kinematic shock analysis, vibration analysis, NASTRAN simulation, LS-DYNA simulation and a full scale drop test. The outcomes from this work are that the structure of EagleCam will survive the impact given that the shock isolation system chosen will mitigate …

Theory and Applications in Macroeconometric Modelling
… Autoregressive (GVAR) models in macroeconometric analysis, particularly in the context of global economic interconnectedness and regional economic differentiation within the United Kingdom. Despite the widespread adoption of GVAR models for their robustness in capturing global economic dynamics, …
