Abstract. In this work, a Ritz formulation for the analysis of damage initiation and evolution in composite plates under progressive loading is presented. The proposed model assumes first order shear deformation theory considers geometric non-linearities through von Karman assumptions. modelled Continuum Damage Mechanics. A set results presented to show potential method highlight some issues be...

This article investigates the three-dimensional magneto stagnation-point flow of ternary hybrid nanofluid caused by a radially extended infinite gyrating disk with multiple slip effects. The main concern is to analyze characteristics heat transport when linear thermal radiation (LTR), quadratic (QTR), and full nonlinear (FNTR) are significant. Ternary fluid composition water, spherical-shaped s...

The current work concerns the study and the implementation of a modern algorithm for error estimation in CFD computations. This estimate involves the dealing of the adjoint argument. By solving the adjoint problem, it is possible to obtain important information about the transport of the error towards the quantity of interest. The aim is to apply for the first time this procedure into Petrov-Ga...

In this study the centre manifold is applied for reduction and limit cycle calculation of a highly nonlinear structural aeroelastic wing. The limit cycle is arisen from structural nonlinearity due to the large deflection of the wing. Results obtained by different orders of centre manifolds are compared with those obtained by time marching method (fourth-order Runge-Kutta method). These comparis...

Fingerprints (epidermal ridges) have been used as a means of identifications for more than 2000 years. They have also been extensively studied scientifically by anthropologists and biologists. However, despite all the empirical and experimental knowledge, no widely accepted explanation for the development of epidermal ridges on fingers, palms and soles has yet emerged. In this article we argue ...

The large deflections of cantilevered beams and plates are modeled discussed. Traditional nonlinear elastic models (e.g., that von Karman) employ restoring forces based on the effect stretching bending, these less applicable to cantilevers. Recent experimental work indicates cantilevers subject inertial stiffness effects. We review a recently established (quasilinear nonlocal) beam model, consi...
