Hi All,
The derivative of C (Right Cauchy-Green Tensor) with respect to F (Deformation Gradient) is computed very easily, but I'm not sure if there is an explicit way to compute the derivative of F with respect to C.

This post contains the equations of nonuniform Timoshenko beam theory, a seconf order finite difference method for the solution of the free vibrations thereof and a Scilab computer program implementation. The implementation also allows for the calculation of static deflection for a user specified load distribution that can also contain point loads. A number of static and free vibration examples are given.
I hope this can be useful to students and others.
Hi guys, i am new to abaqus, just 6 months using it.
Does anyone have a idea on how to define property for kevlar fabric in VUMAT subroutine?
My study is on ballistic impact on soft body armour. I am modelling 9mm FMJ bullet (cooper jacket with lead core) and fabric type choosen is woven fabric which is Kevlar.
Dear imechanicians,
I would like to wish
you a Happy New Year 2012 (Blwyddyn Newydd Dda 2012), and hope
that it will bring you what you seek in life.
The best wishes from our
institute (iMAM) in Cardiff are attached.
In the attachment, you will
find information about the next ECCOMAS Conference on the
extended finite element method (XFEM 2013) and details on the
activities of our institute in 2011.
Finally, I would like to let
you know that our institute is co-organising the following
