ON A SHAPE IDENTIFICATION PROBLEM
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2010, Vol 55, Issue 3
Abstract
An inverse method using a genetic algorithm and a quasi-Newton method is presented in this paper. We consider the problem of identifying a finite elastic airfilled hollow body of unknown shape embedded in a compressible, inviscid homogeneous fluid, based on the concept of time reversal invariance. A nonlinear model describes the acoustical signature of the scatterer. Numerical simulation is carried out for several examples to illustrate the efficiency of the method.

A VIRTUAL INTERNAL BOND MODEL FOR HYSTERETIC MEDIA
In this paper, the properties of the hysteretic media are investigated via the virtual internal bond model (VIB) derived from the hyperelasticity with the integration of the 6–12 Lennard-Jones atomic interacting potentia...
MOTION RECOVERY OF PARALLEL MANIPULATORS USING GENERALIZED INVERSE AND PARTITIONED JACOBIAN MATRIX
In this paper, the motion recovery of parallel manipulators due to joint failure is addressed. The failed joints have either zero velocities, locked joints, or nonzero velocities which are different from the desired velo...
