-dimensional (2D) FE nonlinear analytical model for Fuzhou Basin was established. The peak ground motion acceleration (PGA) and focusing effect with depth were analyzed. Meanwhile, the results by wave...-scale; fluctuation of topography; inhomogeneity site; focusing effect; two-dimensional refined finite element model; nonlinear analysis......
, and then a nonlinear hydroelastic method considering memory effect for ships in irregular waves is proposed. Segmented self-propelling model experiments of a container ship were carried out in a towing tank... of calculation results. This is because the waves which the model encounters are real waves. In this condition, the model motion and load responses are of full nonlinear effects. The mathematical model only......
model when m1=1, m2≠1 When the nonlinear coefficient m=1, the nonlinear Mohr-Coulomb strength criterion is transformed into a linear criterion, and the curved failure surface is degenerated into a flat... the nonlinear MC criterion, the model of overlying 2-layer soil is degraded into a model of single-layer soil. The comparison results of ultimate pullout force and failure mechanism with the upper bound model......
Non-local damage and fracture model of rock and concrete-like materials BI Zhong-wei(毕忠伟)1, 2, ZHANG Ming(张 明)1, JIN Feng(金 峰)1 1.

is well known for good representations of nonlinear dynamic systems [16]. Since T-S fuzzy model has linear dynamics in consequent parts and its output is interpolated by membership functions, its.... In order to design a controller for the nonlinear system Eq. (22), T-S fuzzy model is applied. The T-S fuzzy model of Eq. (21) can be constructed as follows: Rule 1 IF is about a, THEN . Rule 2......
