In this paper we present an improved formulation for the pullout problem, wherein both the effects of fiber end condition and interfacial and frictional shear stresses are considered....
Failure Prediction of Anisotropic Material
Basic mathematical elements of a higher order failure theory for anisotropic material are outlined. Surface closure is ensured by requiring a tensor polynomial to satisfy constraint conditions....
Modeling the Chaotic Behavior in Simple Shear Granular Flows
Simple shear granular flows have demonstrated a variety of puzzling phenomena. Both computer simulations and physical experiments have discovered particle grouping, layering and shear...
Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....
The Analysis Related to the Impact of Composite Panels
In analyzing experiments under impact loading, a dynamic model is needed to solve for the deflections and strains as functions of time. For composites, where shear deformation can be very...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
Modeling 3-D Circulation Using the DSS Technique
The direct stress solution (DSS) technique allows a numerical internal mode solution for the vertical variation of shear stress, rather than velocity, in a three-dimensional circulation...
Probabilistic Evaluation of Bearing Capacity of Shallow Foundations
A probabilistic model is developed to evaluate the bearing capacity of shallow foundations. The bearing capacity formulation proposed by Terzaghi is used but with the bearing capacity...
