On the critical and postcritical behaviour of plane frames

Journal of Constructional Steel Research, 1992
Abstract The aim of the present paper is to show an application of some results of the classical elastica solution for exact critical and postcritical analysis of plane frames. To this effect equilibrium and compatibility equations of perturbed frame configurations are derived.

Planing in Shallow Water at Critical Speed

Journal of Ship Research, 2013
This article summarizes experiments to determine the effect of shallow water on flat-bottomed prismatic hulls towed fixed in heave and trim over a wide range of speed regimes. The experimental design allowed for the separate measurement of pressure forces normal to the bottom and viscous forces tangential to the bottom.

CRITICAL PLANE APPROACHES IN HIGH-CYCLE FATIGUE: ON THE DEFINITION OF THE AMPLITUDE AND MEAN VALUE OF THE SHEAR STRESS ACTING ON THE CRITICAL PLANE

Fatigue and Fracture of Engineering Materials and Structures, 1998
Critical plane approaches are useful methods when designing against long‐term fatigue of machine components made from metals. Somewhat surprisingly, the very basic problem of the evaluation of the amplitude and mean value of the shear stress acting on the critical plane is still not resolved satisfactorily for non‐proportional cyclic loading conditions.

Temperature dependence and anisotropy due to twin planes of the critical current inab-plane

Czechoslovak Journal of Physics, 1996
We report the observation at different currents of voltage-angle characteristics (VAC) of flux creep in YBaCuO single crystals with unidirectional twins in the presence of the magnetic fieldH=1.5 T applied ina−b plane and directed in a small angle range near twin planes (TP).

Nonuniversal and surface critical behavior near a defect plane

Physical Review B, 1989
The existence of nonuniversal, as well as surface (universal) critical behavior near a defect plane is demonstrated on a one-dimensional quantum lattice gas model, belonging to the two-dimensional Ising universality class. According to numerical results the weak defect region is attracted by a line of fixed points starting at the bulk critical point ...

Influence of twinning planes on upper critical fields

Zeitschrift f�r Physik B Condensed Matter, 1991
Within the framework of a Ginzburg-Landau theory for a scalar order parameter, we discuss the effect of the presence of twinning planes on the behavior of the upper critical field as function of the temperature. In particular we study the case of a finite array of planes in the region of weak magnetic field, both from the analytical and the numerical ...

CRITICAL LOAD AND POST-CRITICAL BEHAVIOUR OF LAMINATED PLANE BEAMS

2008
Object of this research is the analysis, within the framework of finite displacements, of laminated plane beams both with straight or curved axis. For such structures, as it is well known, non-negligible transverse shear stresses arise, so that shear strains become an important issue. In the present work a hybrid-mixed finite element model with assumed
