A Combined Experimental/Analytical Approach to Support the Design of a Lightweight, Rigid-Wall, Mobile Shelter

Abstract

Sandwich panel construction (SPC), which Is widely utilized in aircraft design, is particularly advantageous for meeting the stringent structural and weight requirements of lightweight, mobile, military systems. Mobile, rigid-wall shelters must be certified for several transport loading environments, including rail impact (vehicle mounted and dismounted), drop shock, mobility, and external air transport. This technical report documents an Investigation into the survivability of an SPC mobile, rigid-wall shelter after it has been exposed to a conventional air blast event. This study used a combined experimental/analytical approach at the material and substructural levels to (1) generate accurate shelter models, (2) validate the material and substructural models, and (3) maximize the shelter's global performance against a conventional air blast event early in the design stage to avoid costly physical tests.
