G value for design
Hi all,
I want to know how the G(Gravity) value will taken as 4g or 3g for the design of the structures.
On what basis the value will be selected.
Any calculation or theory about it, plz tell me.

SES 2010 Annual Technical Meeting - Call for Symposia
Dear Colleague:
The Society of the Engineering Science is sponsoring the 47th Annual Technical Meeting (SES2010) on October 4-6, 2010 at Iowa State University in Ames, IA. The meeting is held on biannual basis as a standalone meeting to foster and promote the exchange of ideas and information among the various disciplines of engineering and the fields of physics, chemistry, mathematics, bioengineering and related scientific and engineering fields.
finite difference solution of convective boundary layer flow
Hi
i want to solve convection boundary layer flow past a vertical plate problem using Finite difference method, that is, i have to solve momentum (NavierStokes) and energy equations. Most of the boundary layer problem is solved by similarity transform method. That is they convert PDE to ODE then they solve ODE by Runge Kutta Shooting method. I would like to solve the PDE directly.
Momentum Eqn
U_t+U U_x + V U_y = U_yy + Gr T
Energy Eqn

Structure of Defective Crystals at Finite Temperatures: A Quasi-Harmonic Lattice Dynamics Approach
In this paper we extend the classical method of lattice dynamics to defective crystals with partial symmetries. We start by a nominal defect configuration and first relax it statically. Having the static equilibrium configuration, we use a quasiharmonic lattice dynamics approach to approximate the free energy. Finally, the defect structure at a finite temperature is obtained by minimizing the approximate Helmholtz free energy. For higher temperatures we take the relaxed configuration at a lower temperature as the reference configuration.
Help
Can anybody help me with piezoelectric modeling using abaqus cae? I am pretty new on this, I am looking at tutorials or *.cae files but I cannot find any. can you please reference me where to find them or maybe explain how it works? Thanks
cylinder with circumferential crack
hi...i m doing 2nd year mtech...i m getting an error while solving circumferential crack in cylinder using ANSYS...while calculating stress intensity factor(SIF) it shows the error as "all crack face nodes do not have the same z value in the currently active coordinate system"...please anyone let me know how to deal this error??
