Experimental notch fracture testing to calculate KII
Hi,
I am doing a v-notch fracture testing (experimental) with opening angles from 0,30,60,90,120 to 150 deg and need to calculate KII. I need a equation that could be used to calculate KII for both 0 deg and also for non-zero opening notch angles. I am using TestResources machine to do this shear testing and I will get results in terms of load vs. d. The material is PMMA. What could be the appropriate displacement/min or load to break the specimen.
