Quigley Scientific: Dynamic Fracture Analysis of a Polycarbonate Ampoule Device


Dynamic Fracture Analysis of a Polycarbonate Ampoule Device


The dynamic fracture of a polycarbonate medical ampoule device was studied. An extensive test program was designed with the client to investigate the possible correlation of mold pressure at fixed temperature on the fracture toughness of the design. The study involved photo-elastic analysis of 1000 molded specimens under various molding conditions. A presentation of the large graphical database of digital scans of the photo-elastic images was completed as a customized web site for the client. The project increased the understanding of the influence of the mold core design to the temperature gradient induced residual stresses in the molded parts. The organization of the large graphical data set facilitated communications between the US and Europe based offices.
