Monte Carlo Simulation

Submitted by George Papazaf… on

Ask iMechanica

Hello everyone,

I am new to probabilistic assessment methods of structures of various kinds, and I have encountered a paper which includes results of "Monte Carlo Simulation" and also fragility curves. Could someone please recommend to me some books, papers, or even links and sites from where I can learn more about this probabilistic method and for the derivation of fragility curves? My email is gpapazafeiropoulos [at] yahoo.gr (gpapazafeiropoulos[at]yahoo[dot]gr).

Geometric Nonlinear FEM
Hi I am working on numerical simulation of petroleum pipeline subjected to
seismic hazards. I have developed Geo-Nonlinear FEM code for load
controlled which i have compered with Ansys and it is working fine.
now i would like to apply fault  displacement for this i need to
convert my code to displacement controlled using penalty approach
but it is not converging. i will be very happy if any one can suggest
how i can over come this problem or plz sugest me some book or papre. here I am using Newton-Raphson method 
 

3D Doctor Tool

DICOM

Hi,

 

I hope this is the right forum to get some help for my work. 

I am looking at CT data (DICOM files) to make FEM models. To generate 3D surface/volumes for FEM, I was looking for softwares. They all are pretty expensive (4-10K USD). I have decide togo with Able Software's 3D-DOCTOR. I am lookign for some reviews or user experience or comments for this tool.

 

Thanks

Hi there,

 

I am trying to model the DMA test for single pulp fiber. In this research I can I assume whatever procedure or materials parameters I need, from an old PhD thesis I took some materials parameters for the cellulose, hemicellulose and lignin and by using the composite theories I calculated the stiffness matrices for each constituent I have and from there I calculated the stiffness matrix of the fiber, and of course calculated the longitudinal young’s modulus of the fiber at the room temperature.

Hi,

I'm a fresher in abaqus. Now I'm trying to simulate the damage of brittle kind of materials, like concrete with abaqus on mesoscale. But there are some problems now...

The potential for Vanadium in molecular dynamic simulation

One of the most significant factors in molecular dynamic simulatin is to choose the proper potential. Recently, I did some searching jobs on Vanadium (V) potential and finally decided which potential I am going to use. Here is a simple summary:
