So far, we have examined theforce-basedapproach to enforcing constraints. We calculate the constraint forces, apply these forces on the bodies together with the external forces, and integrate them using the methods we described in Part I to simulate the resulting motions. There is, however, anot...

The framework (G,p) is infinitesimally d-rigid if the only infinitesimal motions arise from isometries of Rd. The rigidity matrix R(G,p) of the framework (G,p) is the matrix of coefficients of this system of equations for the unknowns p˙. Thus R(G,p) is a |E|×d|V| matrix, ...

Accept all cookies Abstract We study the stability of shear flows of an incompressible fluid contained in a horizontal layer. We consider rigid–rigid, rigid—stress-free and stress-free—stress-free boundary conditions. We study (and recall some known results) linear stability/instability of the ...
The original feature of the setup is its capability to simultaneously induce inflow and dynamical pitching motions to large scale innovative appendages, and measure strains and hydrodynamic performances. The dynamic stall regimes of two hydrofoils are studied by means of the influence of the Reynolds ...
Interpolation Constraint Element Description:Defines the motion at a reference grid point as the weighted average of the motions at a set of other grid points. Format: 12345678910 RBE3EIDREFGRIDREFCWTG1G2 G3G4... Example: 12345678910
Stages I, II, and III are identified as the motions from A to B, B to C, and C to D, respectively. In view of the kinematics of the Tsaoling landslide, we idealize the Tsaoling landslide as follows. (1) In Stage I (from A to B in Figure 3b), the landslide movement is ...
Knowles and Jakub [38] studied spherically-symmetric motions of an elastic solid containing a spherical cavity and subjected to large strains (e.g., rubber-like materials). A perfectly plastic medium was described by a general strain energy function. Thus, two special cases were solved: Mooney ...
The results show that with some parameters three systems exhibit a very similar dynamic behavior, i.e., quasi-periodic and even chaotic motions. Keywords: parametric pendulum; Lyapunov exponents; quasi-periodic behavior; Chaos1. Introduction Mechanical engineering or other fields always require ...
