in this present work, the kudryashov method and the functional variable method are used to construct exact solutions of the complex kdv equation. the kudryashov method and the functional variable method are powerful methods for obtaining exact solutions of nonlinear evolution equations.

In recent years, more and researches have been carried out on the erosion mechanism of abrasive particles target materials in waterjet cutting process. However, effect material property factors damage is rarely studied systematically. this work, a 3D smoothed particle hydrodynamics-finite elements model established for simulation. The controlled variable method used to study how each factor aff...

Fatigue characteristics of asphalt binder have an important role in asphalt mix resistance against cracking. Viscoelastic Continuum Damage (VECD) analysis of asphalt binders has been successfully used in highway research works in order to predict fatigue behavior of hot mix asphalt (HMA). In this method an intrinsic property of the material, called damage function is obtained which is independe...

The design of released microstructures depends on accurate knowledge of residual stresses and associated elastic constants. The MIT-developed material test procedure, M-Test, uses the variation of pull-in voltage with beam length to extract residual stress and elastic modulus from in-situ test structures. This thesis reports a fully automated computer-microvision procedure that automatically de...

Fabricationand measurement-induced stresses in surface micromachined structures are investigated by wafer-level probing of electrostatically actuated polysilicon test structures fabricated by the MUMPs process of MCNC. The test structures are based on M-Test, an electrostatic pull-in approach for monitoring process uniformity and reproducibility, and, when used in conjunction with suitable geom...

A method for ultrasonic measurement of friction material elastic constants was evaluated through a round-robin process. The purpose of the study was two-fold: 1) to formulate and evaluate a standard test method (SAE J2725) for measuring elastic constants using ultrasound and 2) to quantify the measurement variability when the testing method is applied by multiple operators and instrumentation. ...
