Failure Analysis in Vehicular Crash Reconstruction

Abstract

MIROS has been involved in crash investigation and reconstruction since its inception in 2007, and its efforts have provided valuable evidence in improving road safety in Malaysia. In reconstructing a vehicular crash, applying forensic engineering principles is crucial in understanding the cause of failure, especially mechanical and structural failure. This paper discussed several mechanical and structural failures frequently encountered in high-profile cases investigated by MIROS. The cases used in the discussion are obtained from the MIROS Crash Investigation and Reconstruction Database (CIRD). Among the cases highlighted include heavy passenger vehicles with
substandard production quality and poor maintenance and road barriers built not according to proper safety protocols. Based on the findings, improvements or interventions made are highlighted. The paper also deliberates on objectives and the means of failure analysis in crash reconstruction.
