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 […]

Correctly Scaling Models for SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

In many instances, physical testing, especially in the field of aerodynamics, must be done on a scale model instead of the full size, not everyone can have NASA’s wind tunnel. The “Scale” command in SolidWorks allows a body to be scaled down(or up) to similarly recreate the physical scale model.  However, it is very important how you adjust the forces in a Simulation to correctly pattern the actual forces experienced by the scale model.  In my example I will use […]
