Abstract
The expedient estimation method based on photoviscoelastic analysis for residual stress and residual strain generated by quenching both upper and lower surfaces of polyurethane-resin beams has been discussed.The results obtained are summarized as follows;(1) The fundamental formulae for residual stress and residual strain, which could be estimated expediently from the residual fringe order observed, were derived by introducing the 4-element photoviscoelastic model.(2) The residual stress and residual strain calculated by substituting the residual fringe order obtained from simulated calculation, based on linear-photoviscoelastic theory, into the derived formulae corresponded remarkably with those values obtained directly from simulation.The results obtained here might be useful for the establishment of expedient estimation procedure of residual stress and residual strain in general thermosetting resin moldings.
