Analytical Study of Piezoelectric Actuated Laminates under Transverse Loading
This paper deals with analytical solution of piezoelectric laminated composite plates with arbitrary lamination and boundary conditions subjected to electromechanical loadings. A new first-order shear deformation plate ...
U-Bending Analysis with an Emphasis on Influence of Hardening Models
In this paper the effect of different hardening models in simulating the U-bending process for AA5754-O and DP-Steel, taking a benchmark of NUMISHEET93 2-D draw bending, has been discussed. The hardening models considered in simulations are...
A Numerical Study on the Influence of Bauschinger Effect on Springback in Reverse Bending
, the Bauschinger effect must be considered to determine accurately the internal stress dis-tribution within the sheet metal after de-formation. In this paper the influence of Bauschinger effect on springback in reverse bending process is investigated numeri...
L-bending analysis with an emphasis on springback
One of the most widely used sheet metal forming process is bending when a planer sheet is plastically deformed to a curved one. This process is widely employed in automobile industry, construction of large spherical and cylindrical pressure vessels...
Static Analysis of Antisymmetric Cross-Ply Thick Laminated Plates Using a Layerwise Theory: The Lévy-Type Solution
The full LWT of Reddy [1] is used to analyze the bending problem of Antisymmetric cross-ply thick laminates with finite dimensions. The solution procedure is based on a generalized Lévy-type solution [2] where two opposite edges of the plates...
Behaviour of Plate Girders Subjected to Combined Bending and Shear Loading
to a bending moment in addition to shear, the determination of the ultimate resistance becomes more complex. Herein, an interaction formula for the ultimate resistance of slender plate girders to combined bending and shear loading is proposed that shows...
Manufacturing of Al-Al2O3-Mg multilayered nanocomposite by ARB process and study of its microstructure, tensile and bending properties
C is suitable temperature for accumulative roll bonding of Al and Mg sheets with nano Al2O3 particles. ARBed composite with Al/5wt.% Al2O3 composite powder showed higher tensile strength while the maximum bending strength was related to the composite containing...
The Influence of Variation Bainite Morphology on the Mechanical Properties of NiCrMo (BOZ) Steel
