The roof panel of the bus could benefit from the use of these structures to reduce impact failures in rollover accidents. The aim of this paper is to design a new configuration of bus roof panels stiffened with multi-layer semi-circular corrugated CFRP plates to minimize structure failure during rollover accidents. An analytical failure equation of Tsai-Hill index for the new proposed panel subjected to dynamic impact loading has been derived. The failure equation was validated using FEM methods and digital image correlation impact tests. According to the roll over impact situation, the multi-layered semi-circular corrugated woven CFRP roof panel displays a positive failure behavior of 89%.</span></span><br> &nbsp; CFRP Plates, Corrugated Woven Plates, Dynamic Loading, Composite Plate Impact Failure, Bus Rollover 4327 4352 http://ase.iust.ac.ir/browse.php?a_code=A-10-795-1&slc_lang=en&sid=1 Mohammad Shirzadifar mohammad_shirzadifar@auto.iust.ac.ir 180031947532846004343 180031947532846004343 Yes PhD Graduated Student at School of Automotive Engineering, Iran University of Science and Technology, Tehran, Iran Javad Marzbanrad marzban@iust.ac.ir 180031947532846004344 180031947532846004344 No Faculty at School of Automotive Engineering, Iran University of Science and Technology, Tehran, Iran
