Three brands of polyester resins available in the Brazilian market were analyzed by means of loaded and unloaded models under different states of stresses and strains, aiming its application in photoplasticity. Leoglass 130 PA and Polylite studied through the variation of their modulus of elasticity and yielding strength with temperature and rate. The mechanical and optical behaviors of mixtures of Crystic 199 (rigid) and 279 (flexible) polyester resins were widely studied through uniaxial, biaxial, bending and bi and tridimensional indentation model tests.
The discussion of the results and of the photoplastic method of strain analysis leaded to the conclusion that this method reached good reliability for its application. However, more research is needed on problems such as the residual elastic stresses and the quantitative determination of the variation of the loaded optical parameter, fe (fringe value).
