Quasistatic Bending of Viscoelastic Channel-Plate Structure

Based on the concepts of the small deformation the channel-plate structure was simplified as one thin plate with elastic foundation.The quasistatic bending problem of the channel-plate was investigated by using the corresponding principle and numerical inversion of Laplace transform.A case of the channel-plate structure in micro heat exchanger was analyzed.The analytical solution of the time-dependent(deformation) and bending stress was compared with the results obtained by FEA.The results show that(the analytical) solution is in good agreement with the numerical simulations.It is feasible to analyze channel plates of microdevices by the present approach.
