I am a part C Mechanical Engineering student and have been undertaking a project investigating the strain sensitivity of a particular glass filled composite.
From my quasi-static results, the stress-strain curves seem to be reasonable and match that of the mechanical material properties supplied by the manufacturer, but during quasi-static tensile test it can be seen that the samples failed just above the gauge section (please see attached).
If my stress-strain curves produce the expected results and I feel that the sample was correctly aligned within the grippers of the Instron testing machine, then what could be an explanation for the point of failure? Could it be the slight misalignment of the specimen in the machine, or is there another explanation?
Thanks,
Ben
