Constrained Moving Least Squares (CMLS) Method

Submitted by Jafar on

Hello,

I wish to ask where to find more references about application of constrained moving least squares method for imposing displacement bounday conditions in meshless methods. The most important advantage of CMLS over MLS is satisfying Kronecker delta function property, Hence such as finite element methods we can impose the essential boundary conditions in meshless method using CMLS approach.

Thank you,

Pressure over closure function for Polyurethane or (nearly) incompressible materials in general

Submitted by Andreas Burger on

Hi,

Is anyone aware of a pressure-overcosure function for (nearly) incompressible materials.

 I am aware of functions for PE and articular cartilage but they do not work with v=0.5.   I have been trying to find similar functions for elastomers, but can't seem to find anything.

 I am grateful for any input.

Dear All,

I'm trying to do creep analysis of thermoplastic in abaqus. just i want know the what are all the FE input required for creep analysis for abaqus(also how to get those data). Please who are worked on creep requested to share the information and its usefull for everyone.

Thanks and Regards

ABAQUS : Programing Sandwich plate with Complex Shear modulus core

Submitted by chlif_med on

Hello;

To study the vibration of a sandwich plate I evaluate the complex shear modulus with the GHM method.

Can you tell me how I can enter the complex shear modulus in ABAQUS:

Gv := 0.142*((w/(2*Pi))^0.494)*(1+1.46*I)*1e6 

(I^2=-1 , w =2*Pi*f  , f: frequency)
