Nonlinear Time Spectral Analysis for a Dynamic Contact Model with Buckling for an Elastic Plate

Abstract

In the present paper a dynamic nonlinear model with contact and buckling for an elasticplate is considered. The model consists of two coupled nonlinear hyperbolic type partial differentialequations. The plate is subjected to compressive and/or tensile moving loads on its edges. The foundationsare nonlinear elastic Winkler and Pasternak models. The initial-boundary value problems forthe model are solved with the use of the time spectral method for spatial discretization and after thediscretization the Newmark- time-stepping iterative scheme for the obtained system of nonlinear ordinarydifferential equations. The model is tested for the Winkler-type and shear Pasternak-type andas well for several values of the physical constants of the foundations.

Mathematical Models with Buckling and Contact Phenomena for Elastic Plates: A Review

“…If the structure is also unilaterally supported by the upper and/or lower elastic foundations with different stiffnesses, then, as discussed in Section 3, the transversal loading q = −p(w, ...), i.e., the dynamic buckling problem, involves contact phenomenon. The cases when the nonlinear foundations are modeled in terms of the nonlinear elastic Winkler-type and shear Pasternak-type are considered in the paper of Muradova and Stavroulakis [39].…”

“…The classical linear and nonlinear plate equations are the main keys for creating various plate models, including delamination of composite plates (Vasiliev and Morozov [27], Stavroulakis and Panagiotopoulos [28], Storakers and Andersson [29], Xue et al [30], and Haghani et al [31]), contact problems (Ohtake et al [32,33], Borisovich et al [34], and Malekzadeh and Setoodeh [35], Muradova and Stavroulakis [36][37][38][39], Muradova et al [40], Fichera [41]), analysis of buckled plates (Ciarlet and Rabier [3], Caloz and Rappaz [42], Matkowsky; Putnick [43], Chien et al [44], Chien et al [45], Muradova [46][47][48], Dossou and Pierre [49]), etc.…”
