Development and numerical implementation of nonlinear viscoelastic-viscoplastic model for asphalt materials
(2009-05-15)Hot mix asphalt (HMA) is a composite material which consists of aggregates, air voids and asphalt materials. The HMA response is typically described to be viscoelastic-viscoplastic, and its response is a function of ... -
The effects of wave groups on the nonlinear simulation of ship motion in random seas
(Texas A&M University, 2006-04-12)Historically, the analysis of ship motion and loading responses has been performed in the frequency domain with both linear response amplitude operators and wave energy density spectra. This method, therefore, did not ... -
Nonlinear aeroelastic analysis of high aspect-ratio wings using the method of numerical continuation
(Texas A&M University, 2006-08-16)This research explores the impact of kinematic structural nonlinearities on the dynamics of a highly deformable cantilevered wing. Two different theoretical formulations are presented and analysed for nonlinear behavior. ... -
Nonlinear AVO Inversion Based on Zoeppritz Equations and Its Applications
(2019-05-15)Amplitude Variation with Offset (AVO) inversion is an effective method to estimate elastic parameters of target subsurface layers. However, most conventional AVO inversions are based on linear approximations of Zoeppritz ... -
Nonlinear viscoelastic behaviors of multilayered (pultruded) composites at various temperatures and stresses
(2009-05-15)This study presents experimental works and finite element (FE) analyses for understanding nonlinear thermo-viscoelastic behaviors of multilayered (pultruded) composites under tension. Uniaxial isothermal creep tests in ... -
Novel Active Magnetic Bearing Control for a High-Speed Flywheel
(2016-07-27)Flywheel energy storage (FES) systems have recently gained momentum in the energy storage industry as a viable alternative to conventional lithium-ion and lead-acid batteries because they have superior energy density, ... -
A PAM-4 VCSEL TRANSMITTER WITH 2.5 TAP NON-LINEAR EQUALIZER IN 65NM CMOS
(2017-12-14)This thesis presents a Vertical Cavity Surface Emitting Laser (VCSEL) based transmitter that uses a nonlinear equalizer to equalize for nonlinear and bandwidth limited behavior of VCSEL. The transmitter employs PAM4 ... -
Superharmonic nonlinear lateral vibrations of a segmented driveline incorporating a tuned damper excited by non-constant velocity joints
(2010-07-14)Linear vibration measurement and analysis techniques have appeared to be sufficient with most vibration problems. This is partially due to the lack of proper identification of physical nonlinear dynamic responses. ...
