Abstract: Ceramic seals are widely used in many severe applications such as in corrosive, high temperature and highly loaded situations especially in hot chemical water-based extreme environments for ...

Abstract: A new solution technique is developed for solving the moving mass problem for nonconservative, linear, distributed parameter systems using complex eigenfunction expansions. Traditional Galerkin ...

Abstract: In studying crack problems in a piezoelectric material, many crack models have been proposed and some fracture criteria have been established. The author of 1 presented a new permeable crack ...

Abstract: The interaction between a screw dislocation and a finite crack in an unbounded piezoelectric medium is studied in the framework of linear piezoelectric theory. A straight screw dislocation with ...

Abstract: Some properties of the J-integral in plane elasticity are analyzed. An infinite plate with any number of inclusions, cracks, and any loading conditions is considered. In addition to the physical ...

Abstract: Three wrong expressions in the paper (1) have been found. Equations (4) and (5) in the paper are written in the forms Display Formulaφ(II)(z)=−iφ′(z), ψ(II)(z)=−izψ′(z)+2iz̄φ′(z),Display ...

Abstract: The influence of in-situ stresses and thermal effects on underground gasification of bituminous coals is studied. Evaluations of temperature profiles, stress magnitudes and stress intensity factors ...

Abstract: In this technical note, results are presented from a series of laboratory experiments involving the enhancement of hydraulic conductivity of clayey sands using ultrasonic excitation. An increase in hydraulic conductivity ...

Abstract: A state-space representation of a dynamic system for one-dimensional sound reflection and transmission is developed. The state-space modeling is the first step for future development of an active ...
