SAINT-VENANT TYPE ESTIMATE FOR THE WAVE EQUATION
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2002 Bu çalışmada hızı azalan bir dalga denklemi için Uzaysal Azalım Kestirimi elde edilmiştir. Yük bölgesinden uzaklaşıldıkça son etkilerin, en azından kısa zaman aralıkları için çok hızlı bir şekilde azaldığı görülmüştür.

Numerical Solution of the Plane Problem of Thermo-Elasticity in Strains [PDF]
E3S Web of ConferencesIn the work, within the framework of the Saint-Venant compatibility conditions, two plane problems of thermoelasticity with respect to deformations are formulated. The closedness of boundary value problems is achieved by considering equilibrium equations

A well-balanced solver for the Saint Venant equations with variable cross-section [PDF]
Journal of Numerical Mathematics, 2015 AbstractIn this paper we construct a numerical solver for the Saint Venant equations. Special attention is given to the balancing of the source terms, including the bottom slope and variable cross-sectional profiles. Therefore a special discretization of the pressure law is used, in order to transfer analytical properties to the numerical method. Based
