A book review by Prof. Jan Achenbach (Northwestern University) is published in the Journal of Applied Mechanics, April, 2014. The book, The Theory of Materials Failure, was authored by Prof. Richard M. Christensen and published by Oxford University Press, 2013.

Dear All,
I want to calculate the limit of the fraction (J-1)/(1-2*nu) when material approach to incompressibility, where nu is the Poisson's ratio and J is the third invariant of the Cauchy-Green deformation tensor. In this case J->1 and nu->0.5, but I can't find any reference, how J depends on nu.
Intuitively, this limit has to be a finite value, as it is known that (J-1)^2/(1-2*nu) -> 0 (under the assumption that there is no hydrostatic pressure). Thanks in advance for any suggestions
Hi,all
Recently,I met some problems about intendation simulation with Ansys.My simulation consider failure and large deflection.But the elements happen to distortion when the defelction became very large. So I have a confusion about how to handle the element distorted. Who have any idea about that?
My simulation is a quasi-static problem, How to use Ls-dyna to simulation this problem if the Ansys can't solve the element distortion efficient? Thanks a lot!
i want to study the force acting on projectile while impact with water.
plz give me idea to proceede this problem in abaqus
Would you believe this story?
To me, that metal - on - metal had large friction, especially with the newest designs, it was clear from the old Sir Charnley studies in Leeds in 1950s published in his gold book.
Anyway, when I looked at ceramic on ceramic joints, I also found evidence of increased friction. Maybe ceramic debris is less toxic?
Please comment. What can we do outside USA to improve the situation?

Partial- and

instability are a common disorder affecting people of all ages. Implanted
cartilage replacements (ICR) have the potential to overcome the limitations of
conventional treatment methods and are a promising approach to restore
functionality of the joint. In spite of some success in engineering
cartilaginous tissue, inferior biomechanical and biochemical properties of ICR

Hi,
I am trying to perform a response spectrum analysis of a tall tower. I work with abaqus 6.10, but i am unsure of how to define a spectrum. there is no spectrum radio button on the create amplitude menu... so i guess i have to edit the keywords.
does anyone have an example of how a spectrum can be defined? i'd be much grateful
