Displacements from Loads Over Rectangular Areas

Identification of Moving Loads on a Rectangular Orthotropic Plate from Strains

A time domain method is presented to identify the moving loads on the bridge deck from measuring strains. The bridge deck is modelled as a rectangular orthotropic plate. The vehicle is modelled as two axle loads moving on the bridge deck. Like all inverse problems, the identification is an ill-posed problem, so a regularization technique is employed to stabilize the solution. This paper gives a...

Stresses and Displacements in Functionally Graded Materials of Semi-Infinite Extent Induced by Rectangular Loadings

This paper presents the stress and displacement fields in a functionally graded material (FGM) caused by a load. The FGM is a graded material of Si₃N₄-based ceramics and is assumed to be of semi-infinite extent. The load is a distributed loading over a rectangular area that is parallel to the external surface of the FGM and either on its external surface or within its interior space. The point-...

Buckling Analysis of Rectangular Functionally Graded Plates with an Elliptic Hole Under Thermal Loads

This paper presents thermal buckling analysis of rectangular functionally graded plates (FG plates) with an eccentrically located elliptic cutout. The plate governing equations derived by the first order shear deformation theory (FSDT) and finite element formulation is developed to analyze the plate behavior subjected to a uniform temperature rise across plate thickness. It is assumed that the ...

From Surface Roughness to Surface Displacements

This paper presents an extension to a measurement system to capture bidirectional refEectance distribution function (BRDF) values and texture maps out of images. The extension will enable the measurement of reflection effects due to surface roughness and additionally extracts a map representing local surface displacements. Different lighting conditions where used to discriminate between surface...
