A Simplified Optical Method for Measuring Residual Stress by Rapid Cooling in Thermosetting Resin Plate
Recently, thermosetting plastics have been more widely used in parts requiring high reliability, such as precision mechanical elements of electric apparatus, structural members on the aircraft and so on. The residual stress and shrinkage of thermosetting plastics in molding are becoming a serious problem these cases. Therefore, it has become necessary to investigate the growth mechanism, method of prevention and evaluation of residual stress and strain.
