Application of Large Increment Method in Plate Analysis

Abstract

Abstract: A rectangular Mindlin-Reissner plate element with the forces unknown was developed based on the large increment method (LIM). In the present paper, The plate element was developed to analyze moderately thick plates using LIM. Some numerical examples were presented and the results were compared with the exact solutions and the solutions from conventional displacement-based finite element methods. The convergence and accuracy of the forcebased plate element using LIM for analyzing the moderately thick plates and thin plate were furthermore verified, and it is also shown that the shear locking for thin plate analysis can be prevented.

Key words: large increment method, plate element, moderately thick plates, displacementbased finite element method, shear locking
