Abstract
The nonlinear analysis of wrinkled/slack membrane structures remains a challenge in research work and engineering practice. Using a general structural analysis framework of the vector-form finite particle method (V-FPM), this paper explores the possibility of a newly developed membrane model being applied for this subject. The fundamental variables are discrete point values, rather than functions. The prominent advantage is that nonlinear iterations and special modifications can be avoided, and thus it is well-suited for treating with the numerical difficulties associated with wrinkles. In addition, in analogy to the basic ideas of plastic modification, a wrinkling algorithm based on Raddeman's model is developed, which conforms with the explicit incremental formulations of V-FPM. Finally two classical examples are presented to demonstrate the feasibility and accuracy of the proposed approach for wrinkling analysis. It reveals that V-FPM could stimulate the wrinkled and slack regions of membranes effectively and give stable results.
