Correlation between elastic and electric properties for cyclically loaded metals

Sevostianov, Igor; Bogarapu, Mahesh; Tabakov, Pavel Y. (Springer, 2005)

A new method of evaluation of the elastic property deterioration due to accumulated damage is suggested and experimentally verified. It is based on the explicit correlations between two groups of anisotropic properties – ...
Correlation between elastic and electric properties for cyclically loaded metals

Sevostianov, Igor; Bogarapu, Mahesh; Tabakov, Pavel Y. (Springerhttp://www.springerlink.com/content/l20466165052553l/fulltext.pdf, 2002)

A new method of evaluation of the elastic property deterioration due to accumulated damage is suggested and experimentally verified. It is based on the explicit correlations between two groups of anisotropic properties – ...
Lay-up optimization of multilayered anisotropic cylinders based on a 3-D elasticity solution

Tabakov, Pavel Y.; Summers, E. B. (Elsevierhttp://dx.doi.org/10.1016/j.compstruc.2005.09.023, 2006)

Exact elasticity solutions are obtained using the stress function approach, where the radial, circumferential and shear stresses are determined, taking into account the closed ends of the cylindrical shell. The system of ...
Multi-dimensional design optimisation of laminated structures using an improved genetic algorithm

Tabakov, Pavel Y. (http://dx.doi.org/10.1016/S0263-8223(01)00109-X, 2001)

The present study demonstrates a new variation of the genetic algorithm (GA) technique for engineering applications. This approach is highly efficient for many classes of engineering problems. The proposed selection of the ...
Refined theory of laminated anisotropic shells for the solution of thermal stress problems

Verijenko, Viktor E.; Tauchert, T. R.; Shaikh, C.; Tabakov, Pavel Y. (Taylor & Francishttp://www.tandfonline.com/doi/pdf/10.1080/014957399281066, 1999)

A new higher order theory of laminated anisotropic shells for the solution of thermal stress problems that takes into account transverse shear stresses is developed.The theory is based on the kinematic hypotheses that ...
A shape control model for piezo-elastic structures based on divergence free electric displacement

Kekana, Marino; Tabakov, Pavel Y.; Walker, Mark (Elsevierhttp://dx.doi.org/10.1016/S0020-7683(02)00611-X, 2003)

A model simulating the effects of the control potential on the static configuration of a piezo-elastic structure is presented. This model is centred on the electric displacement field, which is shown to be divergence free. ...
Stress distribution in continuously heterogeneous thick laminated pressure vessels

Verijenko, Viktor E.; Adali, Sarp; Tabakov, Pavel Y. (Elsevierhttp://dx.doi.org/10.1016/S0263-8223(01)00112-X, 2001)

Stress analysis of multilayered pressure vessels possessing cylindrical anisotropy and under internal, external and interlaminar pressures is given. The special case when the axis of anisotropy coincides with the axis of ...
A technique for optimally designing engineering structures with manufacturing tolerances accounted for

Tabakov, Pavel Y.; Walker, Mark (Taylor & Francishttp://dx.doi.org/10.1080/03052150600843308, 2007)

Accurate optimal design solutions for most engineering structures present considerable difficulties due to the complexity and multi-modality of the functional design space. The situation is made even more complex when ...
A technique for stiffness improvement by optimization of fiber steering in composite plates

Tabakov, Pavel Y.; Walker, Mark (Springerhttp://www.springerlink.com/content/h813074n588177w1/fulltext.pdf, 2010)

A methodology for stiffness improvement by optimal orientation of fibers placed using fiber steering techniques of composite plates has been developed and is described here. A genetic algorithm is employed to determine the ...
Use of piezoelectric techniques monitoring continuum damage of structures

Nhassengo, Sikhulile Khululeka (2011)

The objective of the present study was to investigate if piezoelectric techniques or sensors can be used in monitoring structural degradation. The study considers experimental results and analytical modelling of a ductile ...
