Free Vibration of Composite Cylindrical Shells Based on Third-Order Shear Deformation Theory
Journal of Mathematics, 2021 The focus of this study is to analyse the free vibration of cylindrical shells under third-order shear deformation theory (TSDT). The constitutive equations of the cylindrical shells are obtained using third-order shear deformation theory (TSDT).

TSDT theory for free vibration of functionally graded plates with various material properties
Mathematical Modeling and Computing, 2021 In this work, an implicit algorithm is used for analyzing the free dynamic behavior of Functionally Graded Material (FGM) plates. The Third order Shear Deformation Theory (TSDT) is used to develop the proposed model. In this contribution, the formulation is written without any homogenization technique as the rule of mixture.

Approximate postbuckling analysis of shear deformable laminates
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 4, December 2023., 2023 Abstract In the lightweight design of aircraft, spacecraft and marine vessels, often advanced materials are utilised. Advanced materials such as laminated composites made of fibre‐reinforced plastics show transverse shear deformations if they are considered “thick” or possess little transverse shear stiffness.

Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023 Abstract The local stability of unsymmetric laminated structures is significantly affected by bending‐extension coupling and the comparatively low transverse shear stiffnesses, which have to be included in the structural analysis. If such structures have flat surfaces in segments, they can be investigated with the discrete plate analysis.

Closed‐form buckling analysis of unsymmetrically laminated plates
Proceedings in Applied Mathematics and Mechanics, Volume 22, Issue 1, March 2023., 2023 Abstract The local stability of thin‐walled fibre‐reinforced plastic composite beams can be reduced to individual laminates using discrete plate theory. These individual plates receive a supporting effect from their surrounding structure, which is modelled with rotational restraints. In the present investigation, this buckling problem is described by a
