Numerical Analysis of Flexible Multibody Systems

Simulation of Flexible Multibody Systems Using Linear Graph Theory

This chapter provides a general description of a variational graph-theoretic formulation for simulation of flexible multibody systems (FMS) which includes a brief review of linear graph principles required to formulate this algorithm. The system is represented by a linear graph, in which nodes represent reference frames on flexible bodies, and edges represent components that connect these frame...

Failure Criteria Analysis of Laminate Composite Materials

This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite materials caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with woven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated....

Modeling Intermittent Contact for Flexible Multibody Systems

This paper consists of two parts. The first part presents a complementarity based recursive scheme to model intermittent contact for flexible multibody systems. A recursive divide and conquer framework is used to explicitly impose the bilateral constraints in the entire system. The presented approach is an extension of the hybrid scheme for rigid multibody systems to allow for small deformation...

Sensitivity Analysis of Multibody Dynamics Using Spatial Operators

This paper discusses an approach for sensitivity analysis of multibody dynamics using spatial operators. The spatial operators are rooted in the function space approach to estimation theory developed in the decades that followed the introduction of the Kalman filter. The operators provide a mathematical framework for studying a wide range of analytical and computational problems associated with...
