Over the past few decades there has been a growing interest in designing structural component which is capable of absorbing large amount energy during impact. This so-called absorbers have found common usage many applications such as aircraft, automotive, and road barriers. paper presents crush analysis hollow square beam subjected to axial compression oblique loadings. Quasi-static dynamic numerical analyses using ANSYS finite element commercial package were carried out on various angles loadings applied at edge simulate one actual load cases might occur event The isotropic strain hardening rule Johnson-Cook material models (for high rates) utilized for quasi-static respectively. Validation results good agreement with published confirms accuracy simulation scheme. Parametric study was performed steel tube investigate effect wall thickness, obliquity, impact velocity onto specific absorption (SEA) initial peak load. Based analysis, it observed that SEA increases thickness but linearly reduced when are increased. On other hand, increasing resulted increase both
