Nice Tips for Google Search Engine

Submitted by Anonymous (not verified) on

In the current time computer and internet helps to everyone
in their daily routine. Thousand of people take help from search engine for
getting knowledge from internet per day. Mostly people use Google one of the
biggest search engine in the internet. As a Google user, you must aware about
the speed and accuracy of Google Search. How exactly Google search for the
particular word and give the right results in the front of the user. No doubt
Google is one of the most powerful search engines, and there is millions of

Hypoelastic-plasticity with logarithmic spin

Submitted by Biswajit Banerjee on

In small strain elastoplasticity we start off with an additive decomposition of the total strain into elastic and plastic parts. In terms of strain rates we write



Prior to 1990 most large deformation plasticity algorithms extended this idea by postulating an additive decomposition of the Eulerian stretching tensor (rate of deformation):


 

Derivative of Logarithmic Strain

Submitted by Biswajit Banerjee on

Some of you probably work on problems that involve moderately large strains. An useful strain measure for such problems in the logarithmic or Hencky strain. In particular, if you deal with the numerics of large strain simulations, you will often need to compute the material time derivatives of logarithmic strains.

Dear friends,

 I am new to this this forum. I salute the founders, administrators and content providers of imechanica for putting up such a useful forum. I work on finite element anaylsis of large deformation and contact problems, in particular metal forming and tribology.
