Finite element models utilizing LS-DYNA were constructed in order to examine the deformation mode and load-displacement characteristics of ABSS and hybrid aluminum/carbon fiber reinforced polymer models. Subsequently, an evaluation was conducted on the general parameter pertaining to crashworthiness and the capacity for absorption of energy. The results reveal that an increase in the quantity of Carbon Fiber Reinforced Polymer (CFRP) layers within the stacking sequence of [0,90] affords enhanced potential for energy absorption. Conversely, the stacking sequence of [90] exhibits an incongruity with this trend, and achieves superior energy absorption capacity with a count of 4 CFRP layers rather than 8.</span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:107%"><span calibri="" style="font-family:"><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">The present study indicates that carbon fiber reinforced polymer (CFRP) possessing a stacking sequence of [90] exhibits superior energy absorption capacity under both axial and oblique loading conditions at an inclination angle of 10 degrees. In contrast, the use of eight layers of CFRP with a stacking sequence of [0, 90] is found to yield better performance in achieving both axial and oblique loading up to 10 degrees.</span></span></span><span style="font-size:14.0pt"><span style="line-height:107%"><span style="font-family:"Times New Roman",serif"></span></span></span></span></span></span><br> &nbsp; Carbon fiber reinforced plastic (CFRP), Thin-walled structures, Specific energy absorption (SEA), Crashworthiness, Oblique loading 4225 4235 http://ase.iust.ac.ir/browse.php?a_code=A-10-649-2&slc_lang=en&sid=1 Hamidreza Ghasempoor hamidreza_ghasempoor@auto.iust.ac.ir 180031947532846004186 180031947532846004186 No Ali Keshavarzi ali_keshavarzi@auto.iust.ac.ir 180031947532846004187 180031947532846004187 No Hamed Saeidi Googarchin hsaeidi@iust.ac.ir 180031947532846004188 180031947532846004188 Yes
