Hi,

Nice to meet you,

My name is Thuan, Student in Korea.

I am sudying about composite plate.

Could you send me Matlab code of composite plate?

My email is thuandhnt [at] gmail.com.

Thanks.

(Not sure if this is the correct place for this problem. I also posted the question in Fracture Mechanics Forum)

I’m new to fracture analysis, and I get a problem with the Ansys analysis process with thermal loading.

Can anybody help me in using smeared crack and cohesive zone modeling in concrete for different grades. I was actually facing problem in using the same to identify fracture parameters of concrete using ABAQUS. I will also be helpful if anyone let me know about an alternate method to find fracture parameters of concrete using ABAQUS apart from using models. Thanks in advance.......

Hi,

I modeled a sandwich panel under blast loading with conwep function in abaqus,

My problem is that I want to read the equivalent pressure due to amount of TNT I assembled in abaqus,

Do you have any idea how I can get it?

I know that there is an equation for calculating the pick pressure due to conwep loading but I want to read that in abaqus.

What is the appropriate field output or history output for pressure due to conwep loading?

Tnx

  I wanna get the dispersion relation of acoustic crystals in ABAQUS, so far as I know, the frequencies can be obtained by applying different wave vectors in the IBZ, but I dont know how to opperate in ABAQUS, in what way can we simulate the wave vectors (or the cooresponding wave length) . By applying force or displacement, or acceleration ?

 Attacthed, should I model the whole structure or just the 1st BZ? If the 1st BZ is employed, should the periodic semmetric B.C. be considered in my model?

Any suggestion is appreciated! 

Hi all,

I need to model the acoustic impedance response of an elastic tube ( Acoustic-solid interaction) in the frequency domain. The acoustic impedance is :Pressure/volume velocity.

Here is the idea:

The geometry is a simple closed-end elastic tube. The acoustic load is generated by a piston on one end, sliding inside the tube. To have the frequency response, a unit step function of the displacement is applied to the piston (i.e., DZ=U(t)) and the pressure of the air inside the tube is measured in a time domain (i.e., P(t)) in front of the piston.

Dear users,

I am an aerospace engineering student learning finite element method and Abaqus.

I have been searching on this forum to solve my problem, but I haven't found useful information yet.

Hence, I try to explain my problem as clear as possible hoping that someone would be so nice to give me his opinion.

Hi guys,
