Transverse shear parametrization in hierarchic large rotation shell formulations

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 125, Issue 9, 15 May 2024.
Abstract Consistent treatment of large rotations in common Reissner–Mindlin formulations is a complicated task. Reissner–Mindlin formulations that use a hierarchic parametrization provide an elegant way to facilitate large rotation shell analyses. This can be achieved by the assumption of linearized transverse shear strains, resulting in an additive ...

Bisector and zero-macrospin co-rotational systems for shell elements [PDF]

open access: yes, 2015
A principal issue in any co-rotational approach for large displacement analysis of plates and shells is associated with the specific choice of the local reference system in relation to the current deformed element configuration.

A C0 continuous mixed FE formulation for bending of laminated composite plates based on unified HSDT

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 104, Issue 3, March 2024.
Abstract This study proposes a unified C0 continuous mixed finite element (MFE) formulation for the accurate and efficient prediction of stress components in laminated composite plates relying on Higher Order Shear Deformation Theory (HSDT). This unified form of the MFE accepts any convenient function for the representation of transverse shear ...

Experimental and Numerical Studies on the Vibration of Hybrid Composite with an Edge Crack

open access: yesJournal of Engineering, Volume 2024, Issue 1, 2024.
The hybrid composite plate is increasingly used in marine, robotic arm, and other applications. Edge crack is the greatest common fault in the structural systems during its working time. In this research, the successful fabrications of a hybrid composite of epoxy‐based composites reinforced with bamboo and glass fibers have been done to examine the ...

Numerical Integration of Some Arbitrary Functions over an Ellipsoid by Discretizing into Hexahedral Elements for Biomaterial Studies

open access: yesInternational Journal of Chemical Engineering, Volume 2024, Issue 1, 2024.
This study mathematically examines chemical and biomaterial models by employing the finite element method. Unshaped biomaterials’ complex structures have been numerically analyzed using Gaussian quadrature rules. It has been analyzed for commercial benefits of chemical engineering and biomaterials as well as biorefinery fields.
