Columbia University

Department of Civil Engineering and Engineering Mechanics



The Department of Civil Engineering and Engineering Mechanics invites applications for TWO tenure-track faculty positions to support a Department initiative in Sustainable Engineering. Qualified individuals are sought with expertise in either:

(1) Computational mechanics - with an emphasis on large-scale computing applied to multi-scale, multi-phase modeling of materials (from nano- to macro-scale), and/or mechanics and materials challenges in energy and/or the environment.

How to create a precrack

Submitted by Joe cherian on

precrack

Dear Fellows,

 

I am trying to develop a new testing method for analysing the interfacial fracture toughness.The problem I face is to create a precrack. 

 

if I use a stainless steel substrate and TiN or chromium coating on it, which is the best method to create a precrack?

 Please give your sugestions.

cellular/ porous material simulation software

software
porous material

hi - i'm new to the site and not familiar with material science in particular, however i'm currently looking for some simulation-software for cellular solids/ porous materials/ foam which allows me to evaluate the differentiation of geometry without too much scripting/programming - could anyone please point me in the direction of software available at a reasonable price (as an academic/student licence)/shareware/freeware which has output formats such as STL (Stereolithography), OBJ, DXF, IGES ..

Many Thanks! 

ansys magnetism

Submitted by naveenkulnt on

Could anybody help me out with my problem in ansys magnetic analysis??, Iam trying to do a 3-D magnetic analysis in ansys-10, I have a permenant magnet (a block) on the floor with the N-pole and S-pole along the x axis (x-y plane is the floor), then I have a piece of iron (cylindrical shape) fixed at a height ( in the z direction) to the roof (the magnet is on the floor and the piece of iron is on the roof with a small air gap in between them), please tell me how to simulate the magnetic problem and how to get the magnetic flux density on the iron piece

An interesting question...

Submitted by Ajit R. Jadhav on

See the following site:

And then, think: If you had to answer the same question, what would your answer be?

 

(BTW, I know I have quite a few comments to reply here, but somehow have not been able to find time to do so.... I will, soon enough... Anyway, in the meanwhile, wish you all a happy new year... And oh yes, I think it would  be great if mechanicians could share their answers to the above referred question too.)

Equilibrium equations for large deformations

Submitted by Konstantin Volokh on
education

Lagrangian or referential equilibrium equations for materials undergoing large deformations are of interest in the developing fields of mechanics of soft biomaterials and nanomechanics. The main feature of these equations is the necessity to deal with the First Piola-Kirchhoff, or nominal, stress tensor which is a two-point tensor referring simultaneously to the reference and current configurations.
