Environmental Stress Crazing and Cracking of Transparent Polymers

Download or read book Environmental Stress Crazing and Cracking of Transparent Polymers written by Alex J. Hsieh and published by . This book was released on 1989 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resistance to crack and growth in polycarbonate and poly(methyl methacrylate) is evaluated with several surface active solvents including a component of the universal chemical warfare decontaminant, DS2. A static dead weight loading apparatus is used for experimentation, and linear elastic fracture mechanics (LEFM) is used to interpret craze initiation and crack propagation via compact tension tension specimens. Results reflect relationships based on solubility parameters of the solvents and the polymers. Various structural effects due to environmentally induced degradation of these amorphous thermoplastics are illustrated. (AW).
