## Abstract The impact fatigue behavior of a vinylester resin was studied with a pendulumโtype repeatedโimpact tester especially designed and fabricated for the determination of singleโimpact and repeatedโimpact strengths. A wellโdefined energyโendurance impact fatigue curve was obtained with a pro
## Abstract A series of commercial polystyrenes was tested using an instrumented impact tester to determine the fracture toughness __K__~__c__~ and critical strain energy release rate __G__~__c__~. Over the range of __M__~__w__~, 201,000 to 336,000, __K__~__c__~ increased from 1.38 MN/m^3/2^ to 1.7
