Photo-elastic Determination of Stress-Concentration in a Plate, having Rectangular Notches under Tension

Stress Concentration in an Elastic Cosserat Plate Undergoing Extensional Deformations

Composite Strips with a Circular Stress Concentration under Tension

A series of tensile experiments were performed on S2 glass/toughened epoxy composite strips with a center hole or a pin joint at various temperatures within the range of −60C and 125C. Four different lay-up configurations each of 24 layers: [0°], [0°/90°], [45°/−45°] and [0°/45°/90°/−45°] and four different hole diameters: 1/8”, 1/4”, 3/8”, 1/2” were used in both types of specimens. For certain...

A New Approach to the Study of Transverse Vibrations of a Rectangular Plate Having a Circular Central Hole

In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...

Low Velocity Impact on Relatively Thick Rectangular Plate under In-plane Loads Resting on Pasternak Elastic Foundation

This study deals with the elastic-plastic impact on moderately thick rectangular plate subjected to uniform in-plane compressive loads resting on the Pasternak elastic foundation. The proposed rectangular plates have two opposite edges simply-supported, while all possible combinations of free, simply-supported and clamped boundary conditions are applied to the other two edges. The dimensionless...

A FSDT model for vibration analysis of Nano rectangular FG plate based on Modified Couple Stress Theory under moving load

In present paper, vibration of Nano FGM plate based on modified couple stress and First Order Shear Deformation Theories (FSDT) under moving load has been developed. Basic equations and linear strains are introduced by first order shear deformation theory and Mori Tanaka’s model is used for the plate. The module of elasticity and density are assumed to vary only through thickness of plate. Gove...
