Thanks Mandlebra, that much I understood. I am just trying to understand how and why R1, R2, the planes of R1, R2 and the angle \Phi come into this. I guess my questions are more specifically: 1) How do you determine what R1 and R2 are? 2) How do you determine the plane of R1 and R2...

Hi, I am trying to understand a theoretical problem involving the contact between two surfaces. I have uploaded a screen shot of the mathematical formulations of the solution. I understand most of the solution, except the principal curvatures. I have tried to look up principal curvature...

Hi all, Can someone please help me, I am new to Matlab and I would like to use the following upload to create a 3d surface plot. I download all the files from: http://www.mathworks.co.uk/matlabcentral/fileexchange/28177-3d-surface-plots-from-excel-data-gui Then I open the MainGUI.m file...

Would that help me to integrate this between the numerical limits of d/σ1 and h/σ1? Sorry still confused, could you explain further. Thanks.

Hello all, I have uploaded a .gif of the integral. The limits are just values, as I know what d,h, and σ1 are. d and h are the lower and upper limits defined for the probability distribution function and σ1 is the standard deviation. I have not seen this type of integral before, I am not...

Any input on this anyone? Thanks.

Hello all, I am very much interested in improving my engineering mathematics and have one specific question.. When you are reading papers and books which lay out mathematics do you read each equation, symbol, etc and does this help you to understand the mathematics and engineering better...

"In the book, there is an equation to find the natural frequencies of a simply supported beam under an axial load: omega = (pi^2/l^2)*sqrt(EI/roA)*sqrt(n^4 + (n^2*P*l^2)/(pi^2*EI))" Which book is this from please?

Hello all, Just would like to some input from the engineering world on this. I would like to model the lubrication film between a ball and socket joint using FE/CFD co-simulations. In reality the ball and socket arrangement would be located in a bath of fluid and the fluid would provide...

Yep, problem solved thanks

Hello all, I am new to programming and fortran, I have Intel Fortran 9.1 and using this via Microsoft Visual Studio 2005. To start with I have found a simple exmaple from the a Intel Fortran 90 book. I seem to be able to run a debug, but can't seem to create an executable? Its my first time...

Hello all, This is my first post on this forum, I am trying to find out about Fluid Surface Interaction (FSI), but have not found much information on it, I have two questions at the moment: 1) Can anyone recommend any literature/books on Fluid Surface Interaction? 2) I know that FSI...
