In this work, finite element analysis has been done along with experimental test and conducted using numerical tests of the buckling response quasi-static compressive loading six layers woven cross-ply laminated composite material [0º/90º/0º] centrally square circular cutouts. The effect cut-out shape its size a load were obtained experimentally numerically. Compression experiment performed by ...

Composite materials are used in aeronautical, automobile, healthcare and marine industries due to their high stiffness, higher strength-to-weight ratio long fatigue life. Thin plate plays vital role manufacturing of engineering structures. Components made from composite often subjected damage while working. Buckling can cause loss stability component which subsequently leads failure the entire ...

"…send me a white cane," Henri Matisse exhorted his assistants when he completed the compositions for his illustrated book Jazz. The artist was nearly blinded by working with intense color under the brilliant Mediterranean light of the south of France (1). To protect against glare, he used overstated hues and intense blacks. To overcome incapacitating illness, he invented a new medium, "drawing...

in this paper, simulation and analysis of thin steel cylindrical shells with elliptical cutouts under oblique loading were studied using finite element method. first, the numerical results were validated by the results of experimental test performed by an instron 8802 servo hydraulic machine. also, the effect of cutout angle (θ), cutout size, cutout position (l0/l) and cutout aspect ratios (b/a...

Introduction: The paper addresses thin-walled three-layer plates and panels with cutouts, reinforced an orthogonal grid of stiffeners or rectangular reinforcement parallel to the coordinate lines. In this case, thickness entire structure is taken into account analytically using unit column functions. Purpose study: We aimed build a mathematical model deformation develop method for analysis stab...

This paper presents the design of a switched reluctance motor (SRM) for direct-drive propulsion application light sport aircraft. The SRM is designed to replace 70 kW permanent magnet synchronous used in aerospace with similar dimensional constraints. As means achieving high torque density and efficiency, multi-objective framework optimize geometry parameters motor. In order further reduce weig...
