Is peridynamics a superset of Continuum Mechanics?

Submitted by Mario Juha on Fri, 04/16/2010 - 14:04

Recently, I have found a new theory, called Peridynamics, used to solve, mainly, fracture mechanics problems in materials. But, I am confused about the issue if it is a superset of continuum mechanics or is it a totally new theory that reformulate our previous understanding of continuum mechanics? How do you measure material properties with this theory? Do we need to reformulate our theories to deal with fracture mechanics problems? Is it a totally accepted scientific theory?

Ball bearing

transient analysis

full method

i have to do transient analysis of ball beraing. but i could not get an appropiate tutorial to perform transient analysis using full method or mode superposition method since i cannot apply reduced method. please guide me how to apply the load step and what options to use.

software

Hi,I'm new to ANSYS. i'm working on project of active vibration control using piezoelectric patches using ANSYS .

But i'm finding it difficult in modeling of piezoelectric actuators and the input data required for it(VOLTAGE AND MATRIX).

Can any1 help me?i will be thankful

Multiscale method with model reduction

propper orthogonal decomposition

Model reduction based on Propper Orthogonal decomposition is widely used in Computational mechanics to reduce the number of degrees of freedom in systems. In the attached papers, we introduced a POD-based model reduction in a multiscale framework to significantly reduce the computations.

VUMAT

stressold

hi,

recently,i want to write a delamination law using vumat,but coh3d8 element with a traction-separation has s33,s13,s23.in vumat,stressold(nblock,ndir+nshr),i don't kown if s33 is correspond to stressold(nblock,3),and if s23 is correspond to stressold(nblock,5),

i hope someone can help me.

PhD studies in tribology / contact mechanics

I am looking for a PhD student (RA) in Mechanical
Engineering to start in Sept. 2010. The topic is in modeling in tribology
(biomimetic surfaces, contact mechanics, adhesion). The initial support (RA) can be
provided via INSIC TAPE grant and other sources. Interested persons should send
their resume to me at nosonovs AT uwm.edu. The admission criteria for the PhD
degree can be found at http://www4.uwm.edu/ceas/current_students/graduate_students/index.cfm

Solve 2d diffusion equation

Submitted by xiashengxu on Fri, 04/16/2010 - 01:15

HOW to solve this 2D diffusion equation?

the problem described by these equations is: at time=0, N particles are dropped onto an infinite plane to diffuse. C(r,t) represents the concentration density of particles

The solution is very simple, but I want to see the procedure.

Thank you very much!

contact print in abaqus

Submitted by RenegadeMaster on Thu, 04/15/2010 - 13:20

When using contact print in abaqus, how it is possible to obtain contact press of slave surface nodes to the dat-file? It is easy to get the results of master surface nodes, but in this situation it is not possible to change slave surface to master surface.
