Development of a morphing wingtip based on compliant structures
Chen Wang,Hamed Haddad Khodaparast,Michael I. Friswell,Alexander D. Shaw,Yuying Xia,Peter Walters +5 more
TL;DR: A compliant structure is proposed to change the dihedral angle of a morphing wingtip by introducing unsymmetrical stiffness is introduced in the compliant structure to induce the rotation of the structure.
Low-rank damping modifications and defective systems
TL;DR: In this paper, conditions on rank 1, rank 2 and higher rank modifications are derived which ensure that the modified system is simple, i.e., if none of the eigenvalues of the unmodified system is an eigenvalue of the modified systems, then every rank 1 modification that produces a pair of repeated complex eigen values leads to a defective system.

Michael I. Friswell,Seamus D. Garvey,John E. T. Penny +2 more
- 01 Jan 1997
TL;DR: In this paper, the Improved Reduced System (IRS) method is extended to produce an iterative algorithm for the reduction transformation, which is used to calculate the eigensolutions of a structure.

- 17 Sep 2012
TL;DR: In this paper, the authors examined the dynamics of the elastic inverted pendulum with a tip mass under horizontal harmonic excitation, and studied the conditions when the potential barrier is overcome by the tip mass, and large amplitude oscillations occur, by means of the Melnikov criterion.
Nonlinear Response of an Oscillator with a Magneto-rheological Damper Subjected to External Forcing
TL;DR: In this paper, the dynamics of a single degree of freedom nonlinear model, representing a quarter of an automobile with a semi-active, nonlinear suspension, were examined, assuming that the kinematic excitation caused by the road surface profile is harmonic, the principal resonance and frequency entrainment were obtained for regions of the model parameters.
