I'm not trying to detect the fracture during the test. I have failing stain (Weibull Beta & Eta) for seven different laminates under monotonic spherical bend. The testing is extremely expensive so I'm trying to correlate the B0.1 lives to the base material properties in order to evaluate...
Drawing a straight line between 0 and 2000 ue is not what the standard says to do. The standard says to extend the initial linear portion of the line. That statement is open to interpretation. What if the initial portion of the line is not linear? I don't believe I would have this non...
The graph I attached as the best fit to 5000 ue by least squares. Above 2000 ue I get a different failure mode I don't care about so I've started to truncate to 2000 ue. I've attached another graph with the best fit by least squares to 2000 ue; one line is the best fit and one line is best...
Hi,
I'm trying to measure the Young's modulus as per ASTM standard 638 for reinforced plastics. I have in Instron Machine with Axial extensometer returning load and strain values.
The standard says the following with regards to the calculation of Elastic (Young's) Modulus:
Calculate the...
