Performance of bio-inspired cross-laminated timber under blast loading – A numerical study

Abstract

Cross-laminated timber (CLT) is recently attracting significant attention due to the high demand for environmentally friendly materials. As a result, the number of buildings and structures comprising CLT is increasing. However, CLT exhibits brittle behavior which can be detrimental to its performance under blast loads. The structure of CLT shows a striking resemblance to that of conch shells, which is also highly composed of brittle materials but exhibits excellent damage tolerance. This paper mimics numerous features from the cross-lamellar structure of conch to enhance the performance of CLT under blast loading. Numerous finite element models were developed to simulate the behaviors of bio..
