discontinuities in mesh free methods

Submitted by robilant on
Choose a channel featured in the header of iMechanica

Hello,

I wish to ask where to find literature about introducing discontinuities in the shape functions to simulate cracks in mesh free methods.

I found the visibility criterion, the diffraction method and the transparency method referred in the (I think vey good) survey by Fries and Matthies "classification and overview of meshdree methods" but nothing else.

thank you,

project from solid mechanics

Submitted by tuhin harit on

dear mechanicians,

i am student of btech 2nd year,mechanical from iit roorkee.i am looking forward for doing project work in solid mechanics.i know it's a vast topic and thats why i want your help in guiding me.i have not had this as a subject till now so i am confused about ani idea of project work.please give me some details as to where to start with.very thanks.

Introductory Biomechanics Courses

In the early days of biomechanics, there probably were not many dedicated biomechanics courses and instead a regular mechanics curriculum was studied by people interested in tissues and biosystems. However, now that there are so many dedicated bioengineering programs at Universities throughout the world, it seems as though it is more likely that much of students' basic mechanics knowledge comes through dedicated biomechanics courses. This then in turn raises the interesting question of what is taught in these courses?

The SIAM 100-digit challenge of Bronemann et al: A review

Submitted by Mogadalai Gururajan on

Suppose if somebody asked you the following question, and more importantly, wanted the answer to an accuracy of 100-digits:

  • Problem A: A particle at the center of a 10 x 1 rectangle undergoes Brownian motion (i.e., two-dimensional random walk with infinitesimal step lengths) until it hits the boundary. What is the probability that it hits at one of the ends rather than at one of the sides?


Or, this question (again, demanding the answer to an accuracy of 100-digits):

J-Club participation: advice for students

Now that the Journal Club is getting started, I wanted to post some advice for students who may not have participated in such a forum in the past, either online or in person. The fun of a J-club includes the opportunity to broaden your understanding of the literature of a broad field (like mechanics) by reading carefully-selected groups of papers on small topics of interest to different sub-communities. The challenge in participating in the subsequent discussion is ensuring that you understand the papers sufficiently to participate confidently in the ensuing discussion. This will also prepare you to be a good reviewer for technical journals some day.

Pure shear decomposition of the deformation gradient for finite strain measures

Submitted by tvpc22 on

Hai,

I am wondering about deformation gradient for pure shear decompositions. As i saw much literature on simple shear, I couldn't able to track one on pure shear.

Please some one in this forum provide me with literaure and fine details.

Regards

Venkat 

 

 

New Book "Tissue Mechanics"

Submitted by MichelleLOyen on

A new book, "Tissue Mechanics" by SC Cowin and SB Doty is of potential interest to those from a classical mechanics background considering work in biomechanics. Downloadable versions of the first two chapters are available at the book's website along with a full table of contents and other supplemental information.
