Abstract: This paper develops a technique for finding Lyapunov functions for the class of nonlinear partial differential equations arising from a reactor system which takes into account the coupling of ...

Abstract: Theoretical developments on cavity flow studies are briefly reviewed. Physical and mathematical difficulties involved in cavity flow problems are discussed. Particular attention, with regard to ...

Abstract: Numerical solutions for an isothermal case are presented for the direct extrusion process of a cylindrical body with viscous plastohydrodynamic lubrication at high operating temperature and pressure. ...

Abstract: Rausch's classical formula overestimates the torsional strength of reinforced concrete members to an unacceptable degree. The error is traced to the incorrect determination of the centerline of the circulating shear flow. ...

Abstract: A linearized theory for supercavitating flow through a cascade of cambered blades is developed. Numerical results illustrating various points of interest are presented.

Abstract: This paper contains an explanation for the variation of the “coefficient of friction” in metal cutting. The chip partly sticks to and partly slides over the tool and only in the latter region ...

Abstract: Two-dimensional finite deformations are analyzed by factoring and multiplying the matrices of the linear transformations representing them. A general linear transformation consists of a pure shear, ...

Abstract: This paper compares the two softened-truss models for the nonlinear analysis of reinforced concrete membrane elements: (1) the
