Responses of Bilinear and Impacting Systems Subjected to Regular Waves
The dynamic responses of bilinear and impacting oscillators subjected to harmonic loadings are investigated. Differing from previous studies in which bifurcation diagrams were developed...
Cylindrical Shell Redesign by Large Admissible Perturbations
Redesign (or inverse design) is the problem of defining an objective structural State S2 from its specifications and the known baseline State S1. The large admissible perturbations approach...
Wavelet Transform Analysis of Several Transient or Nonstationary Phenomena in Engineering Mechanics
Several examples of the use of a wavelet transform in the analysis of transient events in mechanical systems are provided. The transform has the advantage over other transient analysis...
Wave Propagation in Fluid Loaded Periodic Structures
Periodic structures, such as rib stiffened plates or cylindrical shells, are frequently used as major structural components in naval and aerospace applications. For these applications,...
Flexible Porous Breakwater
This is a theoretical study of the reflection and transmission of linear waves by a flexible, porous and thin beam-like breakwater held fixed in the sea bed. The breakwater is idealized...
Fracture Toughness of DMMC
The fracture toughness of discontinuous metal matrix composites (DMMC) is always less than the fracture toughness of the matrix, in the same heat treatment or annealed condition. If a...
Fracture Toughness Model of Fiber Reinforced Ceramics
This paper addresses the fracture resistance mechanism in fiber reinforced ceramics, and focuses attention on the specific effects associated with the nonlinear nature of the fiber pullout...
Refined Analysis of Load Distribution Factors for Bridges
