Abstract Based on aπ mR -type variational formulation featuring a cross-depth layered model in conjunction with a mechanical sub-element for simulating the material constitution, the cross-depth plasticity development of the Reissner-Mindlin plate is investigated by following the loading process. A 4-node quadrilateral hybrid-stressc 0-continuous plate-bending element HPT-9β is formulated. Numerical examinations demonstrate its remarkable characteristic behavior in being free from spurious kinematic mode, capable of alleviating “locking” difficulties as the thin plate limit is approached and providing numerical results with remarkable accuracy and computational efficiency over Spilker's counterpart LH4. An elasto-plastic analysis of Reissner-Mindlin plates has justified the validity and effectiveness of the present scheme in depicting the cross-depth plasticity development following the loading process.
