I'm working with a photo polymer resin use blue light to solidifies it. I want to find the Poisson's ratio and shear modulus for solid part after light curing. What testing device or testing method I can use to find these material properties?
ASTM D 7078 for shear modulus. For Poisson's ratio in tension ISO 00527-2, use 5A of 5B small specime geometry. For strain determination we use DIC (digital image correlation) with both methods, but strain gauges will also work.
Read the standards, render models with the specified geometries, print, test.
The your sample can be measured nondestructively with shear gages and the shear modulus can be calculated from the measurements. A shear gage is a kind of strain gage that is used for testing rigid composite materials. And Poisson's ratio of samples like yours can be measured nondestructively with standard strain gages. As Mohammad Abboud has mentioned, stay in the elastic region of the material (no breaking or plastic deformation - only elastic bending)
