The proposed analytical model, the three stages homogenization method “3SHM”, could give better estimations of the effective elastic properties. Firstly, a geometrical modeling of the REV and yarns is done. The undulated parts of yarns are modeled with sinusoidal function. Each yarn is decomposed into by: An analytical model to predict the volume of sand during drilling and production Raoof Gholami 1 *, Bernt Aadnoy 2, Vamegh Rasouli 3, Nikoo Fakhari 4 1- Department of Petroleum Engineering. Material properties are represented in the most general form possible for a (locally) linear elastic continuum, namely the unrestricted set of elements of positive semi-definite constitutive tensors and cost measures based on certain invariants of the tensors. Analytical forms are derived for the optimized material by: An analytical model for the pre-peak stress–strain curve of LWAC was proposed and validated by taking into account the effect of properties of LWA. The validation of model showed that the difference between the experimental and prediction results to be less than %. Thus, the precision of prediction model demonstrated the effectiveness of the method and the potential application of the model for .
An analytical model to predict two-phase critical flow rate is proposed. The model is based upon therm al equilibrium, a "lumped" treatm ent of the two-phase velocity (each phase is represented by a single mean velocity), and upon the neglect of frictional and hydrostatic pressure losses. Analytical Model to Predict Dynamic Responses of Railway Subgrade due to High-Speed Trains Considering Wheel–Track Interaction. and the effects of the rail irregularity and the properties of the subgrade bed were then investigated. It was concluded that the dynamic responses of the subgrade are significant compared with responses induced. (). Analytical Peel Load Prediction as a Function of Adhesive Stress Concentration. The Journal of Adhesion: Vol. 82, No. 1, pp. The aim of this work is to create an analytical model capable to relate the total energy dissipated by a friction material during a bench wear test and data collected directly in a vehicle brake, in order to predict the durability of this component in service life. To attain this aim, the concept of specific wear volume, SWV, is adopted.
The model relies on the geometry of the structure and the tensile properties of the constituent yarn and resin components as input parameters. The model was generalized to predict the properties of any 3DOW structure, made with spun or filament yarn, jammed and non-jammed, which have any weave architecture, including hybrid composites.

Suspended solids in the injection water cause impairment of water injectivity during waterflooding operations. Suspended solids affect reservoir properties and decrease the permeability of reservoir rocks causing an increase of injection pressure and a decrease in water injectivity. Removal of all suspended solids from injection water is an expensive and economically unfeasible process.
