An investigation of laser-welded corrugated-core sandwich beams and plates stiffened with concrete
This thesis focuses on the behavior of a corrugated-core sandwich panel with a concrete top layer under normal loads applied to the concrete face. This sandwich panel is composed of two steel face plates separated by a ...
An approach for efficient analysis of drill-string random vibrations
Lateral vibrations are widely recognized as the leading cause of drill-string failures in oil well operations. The finite elements method formulation is used for the mathematical modelling. Due to the erratic nature of the ...
Deterministic and stochastic analysis of nonlinear systems with Biot hysteretic damping
Time domain analysis of nonlinear systems with hysteretic damping is conducted. Specifically, the viscoelastic model proposed by Biot is examined. This hysteretic element represents an integral transform in the time domain. ...
A Monte Carlo study of vibration isolation systems using linear and nonlinear multiple tuned mass damper oscillators
The vibration isolation effect of linear and nonlinear single degree of freedom oscillators attached to a structure is studied. This system of oscillators, directly attached to the main structure, induces a decrease to the ...
