Multiple interacting three-dimensional flaws in electromagnetothermoelastic coupled multiphase composites by extended hypersing
This work presents extended hypersingular integral equation (E-HIE) method to analyze the multiple interacting three-dimensional mixed-mode flaws problem in electromagnetothermoelastic coupled multiphase composites (EMTE-CMCs) under extended electro-magneto-thermo-elastic coupled loads through intricate theoretical analysis and numerical simulations.
Where to get software to make a screen cast
First of all, you might ask what is a screen cast? Well a screen cast is a video of your computer screen. Below is an example of what a screen cast is.
Question: calculate normal to a parabola
Hello:
I need advice on how to calculate the coordinates of a vector normal to a parabola section. The parabola is defined by 3 points on a plane: (x1,y1), (x2,y2), (x3,y3). I need to calculate the coordinates of the end point of the normal vector with the starting point (x2,y2) and a precribed magnitude A.
Any help would be greatly appreciated.
Thank you.
David.

"Students Turn"
Here is a hot topic" Overlaps in our knowledge structures " on iMechanica for all of the students!! This belongs to how students iMechanica can be developed or how students can improve it! Please read the comments and let the others know your ideas about this developements. You will find some suggestions there also. With all students ideas collected, there will be a solution to improve current situation for students section. I can say that page and comments are just for students to say how they like their iMechanica to be.

Metal cutting
I am in the industry of Metal cutting, about Truning, milling, drilling... Mainly on solid carbide now. But new CBN, cermetal, ceramic are also great complementarities.
Hope I can join you and discuss about new tec in this field
