This study investigates the static instability of a cracked plate in subsonic airflow. The model is an inverted cantilever plate, where its leading edge free and trailing clamped. A mathematical crack developed using Dirac function, while Theodorsen aerodynamic mode applied for fluid force. To account angle discontinuity caused by cracks, Fourier expansion employed to transform form correspondi...

A novel and effective formulation that combines the eXtended IsoGeometric Approach (XIGA) and Higher-order Shear Deformation Theory (HSDT) is proposed to study the free vibration of cracked Functionally Graded Material (FGM) plates. Herein, the general HSDT model with five unknown variables per node is applied for calculating the stiffness matrix without needing Shear Correction Factor (SCF). I...

The Kirchhoff-Love plate theory is appropriate for analysing thin structures. In a simple form, only one degree of freedom (per node) needed to describe the behaviour plate, thus saving computational cost. Besides, analysis cracked structures important because it related lifetime Therefore, this paper uses extended radial point interpolation method (XRPIM) investigate free vibration plate. XRPI...

The goal of this research is to carry out a 3-dimensional finite detail approach evaluation composite plate cracked under thermal loading. results the mechanical properties composite, orientation angle fibers, geometric form plate, loading and crack length had been studied show their influence on variation integral J. It concluded that J increases with increase size, temperature reduce in fiber...

In this paper, the problems of composite-patch repair of (i) center and edge-cracked panels loaded in the far-field; and (il) cracks emanating from pin-loaded fastener holes, are examined in thorough detail. The effects of various non-dimensional design parameters on the reduction in the stress-mtensity factors near the crack-tip are determined, and are presented in the form of design charts. B...
