Collective behaviour and spacing of necks in ductile plates subjected to dynamic biaxial loading

Failure of Fibrous Composite Plates under Static Biaxial Planar Loading

This paper outlines an experimental investigation carried out for the analysis of failure mechanisms in fibrous laminated composite plates containing stress raisers, in the form of cutouts, under static biaxial planar compressive loadiing. A specially designed biaxial loadiing frame was used to test a series of 48 ply graphite/epoxy composite laminated plates with centrally located circular hol...

Prediction of Deformation of Circular Plates Subjected to Impulsive Loading Using GMDH-type Neural Network

In this paper, experimental responses of the clamped mild steel, copper, and aluminium circular plates are presented subjected to blast loading. The GMDH-type neural networks (Group Method of Data Handling) are then used for the modelling of the mid-point deflection thickness ratio of the circular plates using those experimental results. The aim of such modelling is to show how the mid-point de...

The Behaviour of Rollover Protective Structures subjected to Static and Dynamic Loading Conditions

BUCKLING ANALYSIS OF FUNCTIONALLY GRADED MINDLIN PLATES SUBJECTED TO LINEARLY VARYING IN-PLANE LOADING USING POWER SERIES METHOD OF FROBENIUS

In this paper, buckling behavior of moderately thick functionally graded rectangular plates resting on elastic foundation subjected to linearly varying in-plane loading is investigated. The neutral surface position for a functionally graded plate which its material properties vary in the thickness direction is determined. Based on the first-order shear deformation plate theory and the neutral s...

Determination of Residual Stress for Single and Double Autofrettage of Thick-walled FG Cylinders Subjected to Dynamic Loading

In the present article a numerical procedure is developed for dynamic analysis of single and double autofrettage of thick–walled FG cylinders under transient loading. The governing differential equations are discretized and presented in explicit Lagrangian formalism. The explicit transient solution of discrete equations are obtained on the meshed region and results for stress and strain distrib...
