In this paper, the first-order shear deformation plate (FSDT) model is exploited to investigate the mechanical behavior of laminated composite and functional graded plates. Three approaches are developed to transform the laminated composite plate, with stepped material properties, to an equivalent functionally graded (FG) plate with a continuous property function across the plate thickness. Such transformations are used to determine the details of a functional graded plate equivalent to the original laminated one. In addition it may provide an easy and efficient way to investigate the behavior of multilayer composite plates, with direct and less computational efforts. A comparative study has been developed to compare the effectiveness of the three proposed transformation procedures.

In the theory of dislocations, the Burgers vector is usually defined by referring to a crystal structure. Using the notion of affine development of curves on a differential manifold with a connection, we give a differential geometric definition of the Burgers vector directly in the continuum setting, without making use of an underlying crystal structure.

The long range elastic interaction between dislocations is naturally accounted in
discrete dislocation plasticity through stress field of individual dislocation.
In addition, the dislocation boundaries elastic interaction is considered via
image stress superposition approach in the finite element framework. In current
study these interaction terms are considered in crystal plasticity framework
through length scale dependent internal residual stresses which are arise from

hello everyone..i am a beginner in this field so ultimately seek help in order to escalate in my research.Currently i am working on hybrid composites using graphite filled FRPCs so kindly encourage me and help me make up my mind for better understanding in order to have an effective research.I am concentrating on tribological properties and if there is anything i can possibly implement to make it more profound please guide me so.I am working on my theoratical thesis right now.
