Composite Materials
Experimental evaluation and estimation of frictional behavior of polymer matrix composites

Hiral Parikh; Piyush Gohil

Volume 10, Issue 2 , April 2021, , Pages 473-483


  As the fiber-reinforced polymer matrix composites give good strength and can work in rigorous environmental conditions, nowadays, more focus is given to study the behavior of these materials under different operating conditions. Due to the environmental concern, the focus on the natural fiber reinforced ...  Read More

Experimental and finite-element free vibration analysis and artificial neural network based on multi-crack diagnosis of non-uniform cross-section beam

B. Asmar; M. Karimi; F. Nazari; A. Bolandgerami

Volume 5, Issue 1 , December 2015, , Pages 1-11


  Crack identification is a very important issue in mechanical systems, because it is a damage that if develops may cause catastrophic failure. In the first part of this research, modal analysis of a multi-cracked variable cross-section beam is done using finite element method. Then, the obtained results ...  Read More

Large amplitude vibration prediction of rectangular plates by an optimal artificial neural network (ANN)

Mahdi Karimi; Alireza Shooshtari; Soheil Razavi

Volume 4, Issue 1 , December 2014, , Pages 55-65


  In this paper, nonlinear equations of motion for laminated composite rectangular plates based on the first order shear deformation theory were derived. Using a perturbation method, the nonlinear equation of motion was solved and analytical relations were obtained for natural and nonlinear frequencies. ...  Read More
