Unbiased stereological methods were used in conjunction with microcomputed tomographic (micro-CT) scans of human and animal bone to investigate errors created when the parallel plate model was used to calculate morphometric parameters. Bone samples were obtained from the human proximal tibia, canine distal femur, rat tail, and pig spine and scanned in a micro-CT scanner. Trabecular thickness, t...

Subducting plate (SP) curvature exerts a key control on the amount of bending dissipation associated with subduction, and the magnitude of the subduction-resisting bending force. However, the factors controlling the development of SP curvature are not well understood. We use numerical models to quantify the role of SP rheology on the minimum radius of curvature, Rmin. We find that Rmin depends ...

In order to quantitatively evaluate the shear-bearing capacity of shear connectors of square concrete filled steel tube (CFST), push-out tests on 14 square CFSTs with shear connectors have been carried out. Among the 14 CFSTs, there are 13 specimens with steel plate connectors and one specimen with steel bar connectors. The following factors are investigated to figure out their influences on th...

In this paper the recently developed semi-analytic method to solve the free-surface wave interaction with a thin elastic plate is extended to the case of a plate of finite thickness. The method used is based on the reformulation of the differential-integral equation for this problem. The thickness of the plate is chosen such that the elastic behavior of the plate can be described by means of th...

Abstract This article used the strip element method to study dynamics problems of functionally graded plate with variable gradient parameters under harmonic loads. The dynamic model is established by using method, rationality and accuracy theoretical results are verified finite displacement response different also calculated. show that parameters, varies harmonically time, increase fluctuation ...

In this present study, we are interested in the use of a precise theory shear deformation for buckling analysis plates with functional gradation simply supported such as refined four variables. Several parameters comparison have been used, dimensional and nondimensional. The displacement field is compatible nonuse correction factors satisfied, choice material very way variable according to thic...
