Stratasys 3D Printing: Photoelasticity with PolyJet

EmailFacebookLinkedInTwitterShare

Photoelasticity with PolyJet   Photoelasticity is a visual method to determine the stress distribution of a part geometry.  Unlike analytical methods of stress calculations, photoelasticity gives a fairly accurate picture of stress distribution around any imperfections in the actual geometry.  This method can be an important tool for identifying critical stress concentration in irregular geometries.   The principal of photoelasticity is based on rays of light passing through certain transparent materials with two refractive indices to create a phenomenon of an isochromatic image […]
