I am using PC/ABS for a plating application would like to check the molded-in stress of the part by a process similar to the following.
ASTM D 1939-84, "Determining Residual Stresses in Extruded or Molded Acrylonitrile-Butadiene-Styrene (ABS) Parts by Immersion in Glacial Acetic Acid"
I am not...
Great advice. I will come at this from the molding end. There are several things in part molding that can cause plating issues. Any mold release agents used or touching the parts without gloves can cause oils to be deposited on the surface which will affect plating. Any excessive molded in...
I agree with Like2Strike. Something just happened that changed the part that had functioned in the past. I don't know much about HDPE, but I had a similar issue with a nylon part. The material was over dried and this caused a loss in properties. All of the analyses showed that this material...
It seems that you have most of the data you need to get a linear structural analysis completed.
Tensile Modulus = Elastic Modulus or Young's Modulus
Tensile strength at yield = Yield Strength
Elongation at yield = Yield Strain
The Poisson's ratio for most plastic is near 0.35, and this value...
