This recent article presents an improved methodology to calculate in-situ Young's moduli of the constitutive layers in a multilayer systems (e.g. thin films, SOFCs, TBCs etc.)

Geometric nonlinearity

Submitted by peto24ap on

I am trying to write my own code for geometrically nonlinear analysis of mixed structures (cables, trusses, beams...). I would like to have it as general as possible ie. applicable also to 2D and 3D solids. I am trying to follow nonincremental Newton Raphson procedure from Ansys theory manual, but my computation are not converging.. Can I kindly ask you for advice ?

Here is my flow:

=== Linear analysis ===

(1) inv Kt *F = du

resluts are correct comparing to Ansys

=== Nonlinear analysis ===

while (F_ext - F_int) < 1e-3

(2) u = u +du

Experiment.com: Can molecules make music?

Submitted by swcranford on

Experiment.com is a crowdfunding site for research (a Kickstarter for science!).

Open to all, a target amount for a project is set, and funds are raised through small individual donations. The success is based on how many people like your idea. It's kind of a fun/alternative idea to traditional grant sources! If you have an interesting idea, I recommend it.

Discrete and smeared approach

Submitted by kashif355 on
I am structural engineering student , working on discrete and smeared model of 1/4 th scale bridge girder using ANSYS software and facing some problems.
Some problems regarding discrete approach are:
 
1. can I use beam188 instead of link180 for modeling reinforcing steel???
2. what should I use value of shear transfer coefficient for open and closed crack ?? what is criteria for using these coefficient??
