Finite Element Analysis on Energy Absorbing Capability Of W-Beam Corrugated Guardrail

Kemalangan jalan raya adalah salah satu fenomena masalah yang terbesar di dunia dan masalah bagi mencegah sesuatu kemalangan. Rel Adang seperti W-beam Guardrail adalah penghadang jalan yang direka untuk mencegah kenderaan dari meninggalkan jalan tersebut untuk meningkatkan keselamatan jalan raya. Ke...
