摘要
The energy absorption characteristics of E-glass/Polypropylene (PP) isogrid composite panels under quasi-static transverse load conditions have been investigated. Experimental tests and finite element simulations were performed for isogrid composite panels in three-point bending boundary condition. Results of tests and simulations show that loading the panels on rib side results in greater specific energy absorption along with larger displacements compared to skin side loading which is more abrupt. These results can be used to advantage in. weight-critical automotive side impact crashworthy applications. Vibration response measurements which were used as a non-destructive tool for evaluating the quality of as-manufactured isogrid plates and monitoring induced damage in one of the plates are also presented.
