Creep Tutorials using Abaqus

My research area is modeling of creep in MMC. I am trying to use Abaqus for this purpose but I am unable to find any tutorial that can provide me some help that how to use creep module provided in Abaqus. Will any body can help me by providing some tutorial related to that topic. It will be highly apprecioated.

 

 

Project Tuva (Feynman's lecture series)

character of the physical law

Here is an interesting link I came across while searching for the Feynman lectures -- Project Tuva.

http://research.microsoft.com/apps/tools/tuva/

It provides each of Prof. Feynman's seven lectures delivered at Cornell as a part of the Messenger lecture series. This format of posting lectures by Microsoft is absolutely amazing. I hope more such lectures especially videos of keynote lectures in leading conferences and congresses can be made available online.

modelling of rectangular composite plates using ANSYS

Submitted by sharma_avadesh on
education

I have to analyse the carbon/epoxy composite laminate in ANSYS,  to determine the natural frequency of rectangular composite plates. The plate is simply supported . I  am not able to model the composite lay up with the correct orientation of the fibre. so any body have the step by step procedure for modelling the composite lay up in ANSYS and how to determine natural frequencies  please give it to me on my e-mail:  sharma_avadesh [at] yahoo.com

Two-point Tensors

Submitted by Mubeen on

I am confused about the use of two-point tensors in elasticity. The deformation tensor F and first PK tensor are two point tensors, and the "two-point" property arises from use of two different Coordinate System When a continuum body is deformed, why it is necessary to move the Coordinate System as well? (or alternatively, why the coordinate system is attached to the body itself??, isn't it possible to use a general coordinate system which can represent the deformations and also account for the rigid body rotations of the continuum body?).

Hi everyone.

I'm working on my master thesis, dynamic analysis of plates using finite strip method.

I have found one problem (among others) that could be interesting to community.

In the attachment you can find example from Mathematica. There is 21 mode shapes of clamped-clamped beam. Recently i noticed that formulation given in every book about dynamics (Timoshenko, for example) isn't valid for higher modes for any beam that isn't pinned on both ends.

Effect of surface hardness in tensile testing

Submitted by GOPALAERO2000 on

stress strain curve

Hi Everyone,

 Is is possible to account the surface hardness effect in the tensile testing specimen? If possible, how could it be acomplished?

For instance, I would like to establish the  stress strain curve for the material that used on surface hardened component. Will there be a big change if the surface hardness effect is considered on the tensile specimen?

 

Please throw some light in this regard.

 

Thanks

M Gopalakrishnan
