Young Modulus and Yield Strength of low alloy steel

Submitted by romaroma on

Hi all!

What is the relation between young's modulus and yield strength?

In the stress strain curves for our sample indicated  the Youngs modulus is above 400000 MPa. I think this is not ok, since the Youngs Modulus is a constant factor, which should always be at around 200000 MPa. However, the value of yield strength (0.5% EUL) meet the expected value of YS.

Please give advice about this matter? Is that related to error strain reading? Can we say that our YS already OK and neglecting the value of Young's Modulus that given by our Machine?

I would like to share with you my review article titled "Effect of Point and Line Defects on Mechanical and Thermal Properties of Graphene: A Review": http://dx.doi.org/10.1080/10408436.2015.1068160

ABAQUS Subroutine Error

Submitted by JMichael on
software

Good day 

I have encountered and Error within Abaqus Cmd prompt after numerous trial and error installations and path designations. Below is a display message retained from the cmd stating every system environment has been passed but stil no abaqus subroutine available?
Using Abaqus 6.10 +VS2008+Fortran 11.1 installed in that order. Below is a display message from the prompt.
 
Any suggestions would now be appreciated.

Cohesive Zone Model and XFEM

Submitted by Prashanthi on

Hello all,

I am trying to model crack propagation in ABAQUS to simulate four point beam bending test. I am using 3D model. I am using XFEM for propagating the crack. I am not getting the required output parameters ( J-integral and SIF ), instead i am getting only PHILSM and PSILSM. I dont know how to extract the required parameters from these two values. For modelling a crack propagation, whether CZM is reliable or XFEM is reliable??. What are the disadvantages of CZM over XFEM( other than predefined crack path ). Any suggestions will be really helpful. Thanks in advance.

Hyperelastic compressible experiment

compressible incompressible

Dear All,

 

I got confused on the hyperelastic experiment that the uniaxial, equibiaxial, and planar test are based on the material is incompressible. What if the material is compressible, are the experiment the same as incompressible material? Except for the volumetric mode, what is the different between incompressible and compressible material experiment? Thanks!

 

Regards,

Bob
