I have implemented a 2D co-rotational truss formulation in matlab. I get identical results to OpenSEES.
Now I'm trying to implement a 2D co-rotational beam formulation. I have followed the simple formulation in Crisfield's book volume 1. It seems like this should be a fairly straight forward extension of the truss formulation. I have rederived everything Crisfield has done and obtained the same results, yet something is still incorrect.
For a system in thermal contact with the rest of the world, we have described three quantities: entropy, energy, and temperature. We have also described the idea of a constraint internal to the system, and associated this constraint to an internal variable.
A recent paper on JMPS has seriously questioned the foundation of the SGP theory of Fleck and Hutchinson. The matter is not simple, but is it a good bench test for imechanica to discuss?
I am trying to model a boat sitting in the water. I want to see the stress distribution after the boat is put in the water. If I only consider the solid boat model, I need define the weight of the boat and the buoyance otherwise the boat would not be in a equilibrium. My question is that how can I define the buoyance in ABAQUS, or I have to find an alternative to define the floating force? Since the water pressure is function of depth, I think we might be able to define the pressure at different level. But I don't know if it will works fine.Any comment will be appreciated.Thanks a lot.
This is topic 12-21 Advanced Computational Methods for Fracture in the upcoming ASME Congress 2009 (November 13-19, Lake Buena Vista, FL., USA.) Deadline for abstract submissio: March 2, 2009.
I taught this course at the University of California, Santa Barbara, in Winter 1994, Winter 1995, Spring 1996; at Princeton, Spring 2003; at Harvard, Spring 2004. The notes posted here are those distributed to the class in Spring 2004.
I am a freshman in micromechanics area. Many books and papers always say the linear elastic equilibrium equation(Someone also called Navier type function) could be solved with Green Function and Fourier Transformation, but without details. May be the writers think anyone should know these two popular methods in solving the PDE. I have search many books(both mathmatic and mechanics), However, there are little information about solving the navier type function with those two methods.
An essential step to “understand” thermodynamics is to get to know temperature: how temperature comes down as an abstraction from empirical observations, and how it rises up as a consequence of the fundamental postulate. I have just updated my notes on temperature. The beginning paragraphs of the notes abstract temperature from empirical observations. These paragraphs are posted here.
