Abstract
dc:description.abstractAn experimental study is made to investigate the feasibility of determining a viscoelastic stress-strain law for two (or three) dimensional stress conditions by means of one dimensional tests. The conclusions are based upon comparison of theory and experiment for a creep test of a lead plate, subjected to biaxial tension. The stress-strain law that was selected is given by S<sub>ij</sub> = B σ²/σt² e<sub>ij</sub> + c σ/σt e<sub>ij</sub> to cover ehear effects and by σ<sub>ii</sub> = κε<sub>ii</sub> for hydrostatic tension or compression. S<sub>ij</sub> and e<sub>ij</sub> are respectively the stress deviator and σ<sub>ii</sub> and ε<sub>ii</sub> are the stress and strain tensors. Uniaxial test data was used to evaluate the constants in the above laws. The Lapplace transform technique was used to obtain the analytical solution for the strain in the plate as a function of time. Agreement between theory and experiment or the duration of the test, 1200 minutes, was quite good.
