Static and vibration analysis of functionally graded beams using refined shear deformation theory [PDF]
, 2013 Static and vibration analysis of functionally graded beams using refined shear deformation theory is presented. The developed theory, which does not require shear correction factor, accounts for shear deformation effect and coupling coming from the ...

Analysis of functionally graded sandwich plates using a new first-order shear deformation theory [PDF]
, 2014 In this paper, a new first-order shear deformation theory is presented for functionally graded sandwich plates composed of functionally graded face sheets and an isotropic homogeneous core. By making a further assumption to the existing first-order shear

A Joint Model for Graded Responses and Response Times
PsychometrikaAbstract While the joint modeling of item responses and response times (RTs) has received considerable attention, most existing approaches remain limited to dichotomous items and are not applicable to assessments involving polytomous or mixed-format items.

A quasi-3D theory for vibration and buckling of functionally graded sandwich beams [PDF]
, 2015 This paper presents a finite element model for free vibration and buckling analyses of functionally graded (FG) sandwich beams by using a quasi-3D theory in which both shear deformation and thickness stretching effects are included.

Bending and free vibration of functionally graded beams using various higher-order shear deformation beam theories [PDF]
, 2012 In this paper, various higher-order shear deformation beam theories for bending and free vibration of functionally graded beams are developed. The developed theories account for higher-order variation of transverse shear strain through the depth of the ...
