Large deformations of thin plates subjected to impulsive loading
… clamped Circular, square and rectangular steel plates. The final midpoint deflections measured were between 3 and 12 plate thicknesses: and the deflection time history was measured using a light interference technique. While the deflection-time history was being recorded. the impulse was …

A laboratory simulation of low velocity projectile impact on thin plates
… impact behaviour of aluminium and glass laminate plates. The impact response of the laminate plates was compared to that of singular glass and aluminium plates. The apparatus is capable of generating force-deflection curves for the short duration, impact response of a singular 6mm thick glass …

Some mixed and associated boundary value problems in the theory of thin plates
The bending of thin flat plates has occupied the interests of mechanicians and applied mathematicians since J. L. Lagrange discovered the differential equation characterizing the behavior of such structural members. One particular phase of investigation in this field concerns itself with the …

On the Use of Shearing Interferometry for Slope and Curvature Measurements of Thin Plates
… used for the slope and curvature measurement of thin plates. Several methods are proposed for a plate model with a specularly reflecting surface. Slope contours are also obtained for a diffusely reflecting model.

The effect of boundary conditions on the failure of thin plates subjected to impulsive loading
… of edge boundary conditions on the failure of thin plates subjected to impulsive loading. In previous investigations the discrepancy between experimental results and theoretical solutions and effects observed at the edges of deformed plates have brought the method of securing the plate into …

The effect of stand-off distance on the failure of thin plates subjected to blast loads
… on the response of fully clamped circular plates subjected to blast loads. The experimental procedure consists of creating a blast load using disc shaped plastic explosive mounted onto a tube of required length. The length of the tube is the stand-off distance. Different lengths of tubes …

Correlation of localised thermal shock to isothermal biaxial crack growth rates in thin plates of AISI 316 stainless steel.
… covers numerical analyses of edge-cracked thin plates of austenitic stainless steel, AISI 316, loaded with transient thermal downshock. Further to this isothermal centre-cracked plates loaded under isothermal biaxial conditions are modelled. Crack growth rates are then applied to the models …

Measuring particle alignment in particleboard and predicting selected mechanical properties of oriented boards
… The shear model, however, was only effective for thin plates. Poisson's ratio, the tensile modulus, modulus of elasticity, and modulus of rupture increased in the direction of particle alignment as the degree of orientation increased. The shear modulus decreased as the orientation increased. The …
