APPLICATION OF SPLITTING TIME INTEGRATOR FOR DYNAMIC PROBLEM OF MINDLIN-REISSNER PLATE

Abstract

 In this work, the mixed finite element method, in which the transverse shear stresses are taken as unknown variables, is applied to dynamic problems of the Mindlin–Reissner plate. The splitting time integrator that works as an explicit method for bending deformation and as an implicit method for transverse shear deformation is adopted. The proposed approach relaxes the restriction on the time interval of an explicit method for plate bending problems by employing an implicit scheme targeted at only the minor transverse shear deformation. Numerical experiments demonstrated that the proposed approach exhibits superior numerical properties compared to conventional time integrators in terms of time interval and accuracy.
