Stress

This is a picture of a plastic part subjected to polarized light. A horizontal and a vertical polarizing screen are placed in front of and behind a clear plastic manufactured component and light shone through. Stresses inherent in the part from its manufacturing process show up as coloured areas (or grey in this image). Seen at the Medical Design and Manufacturing Show in Philadelphia in May 2012.
