Am having an error:nodes may have incorrect defintions.

the contact is between truss and beam

Doeas anyone know how to solve this error?

My name is Hitesh Pate.I am studing in mechanical engineering(B.TECH) in final year.

I want to integrate some formula for project purpose.But i will not able to integrate that formula.So i need help for this problem.

If anyone have idea about this problem.Please guide to me.

I attach pdf file which contains those formula.

Thanks in advance!!!!!!!!!!!!!

What is the best way to numerically solve the transport equation like(the least numerical diffusion phenomenon):

df/dt+v df/dx=0

 Thank you

It is known that the if the coloumn is long and slender enough, then under axial compressive loading, the column buckles..

But i am wonder, why buckling happens at all?

Can anyone put a light on this.

We all know Euler buckling of a beam under axial thrust, but can buckling occur in an elastic structure in which all elements are subject to tensile dead loading?

We provide a positive answer to this question, see http://www.youtube.com/user/RoyalSociety#p/u/0/EKngs1vvcJU

Dear All,

I am presently deducting formula for a metallic circular plate with large deflection. Can anybody help me how to dedcut the  membrane strain energy of a circular plate?

All information on reference or textbook are all welcome.

Thanks.

Paper surface topography is vital to the intended use and quality of the product. To control paper product quality it will heavily rely upon quantifiable, reproducible and reliable surface measurement. Precise surface measurement and evaluation of a paper product can lead to the best selection of processing and control measures. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to measure paper surfaces.

Dear All,

I am writing to introduce to you a general-purpose composite beam solver, GEBT, which can capture all the geometrical nonlinearity obtainable by the six fundamental deformation modes (extension, torsion, bending in two directions, and shearing in two directions), and the coupling between these fundamental deformantion modes, such as extension-twist coupling commonly existing in initially twisted rotorblades. The features of GEBT are:
