I have a model of a single and multiple piezoelectric fiber(s) with interface crack(s) embedded in an infinite isotropic material medium I would like to study the effect of surface crack contact. Therefore, the crack would still exist but one time we would study when the interface crack prevents penetrations in compression and the other time when there are no contact i.e. similar to harmonic analysis of a crack without a contact. Again when we are studying the contact between interface surfaces of the crack it will work direction wise preventing penetration i.e. when Congressional forces are applied. For the non contact surface the crack would work in both compression and tension in the same manner.

Design powerful high speed Linear DC motor (total width can be 3-6 inches, battery voltage up to 48 V). Example is attached. You don't have to use magnets, it can be salient pole / SRM etc. When you submit bid, mention your previous experience and what kind of speed and force you can achieve as rough estimate. You can use any open source or your favorite software.

Details Title: Efficient finite element methods for natural and mixed convection flows in deformable domains under thermal stresses We can use matalab... Abstract We develop an efficient class of finite element method for modelling deformation of domains in natural and mixed convection flows. At high temperature thermal stresses on the solid enclosures are expected to generate deformation on the domain confining the fluid flows which alter the flow structures. The aim of this study is to develop a consistent model for coupling convective flow, heat transfer and solid deformation in different enclosures. Coupling conditions at the interface between solid and fluid domains are also investigated in this study. Two types of flows are considered in our work using the incompressible Navier-Stokes equations for the first type and Darcy equations for the second type. Linear elastodynamics is used for the deformation of solids in our model. As a numerical solver we develop an efficient finite element method based on Galerkin-characteristic techniques in which same meshes are used for both fluid and solid domains. To speed up the numerical solver we opt for two procedures: (i) mesh adaptation using a criteria based on the gradient of thermal stresses to refine the meshes and (ii) enrichment of basis functions using a series of heaviside and exponential functions in our finite element solutions. The performance of the proposed models and methods is examined and validated using several benchmark problems in the natural and mixed convection flows. my work is about simulation study on very hot fluid(air) flows over a solid, so thermal stresses are applied on the solid that can cause bending and deformation for the solid Navier-stokes equations , Finite element, Galerkin method .... all are used to sole the and do the study in Fortran90 my simulation is on hot fluid (air) flows on a solid, that cause heat transfer and deformation ....... I need to mesh and use finite element method on both fluid which is air and solid of course I will use Navier stokes equations to study the behaviour of the fluid are you fimiliar with Navier-stokes equations?? see this attached file it will help you understanding it---2013-Lecture-6.pdf .. this si the file we need to implement. you see we wil do the simulation study on both the fluid as well as the solid
