Hi everyone,

I am new in IMECHANICA. I am a MS student, doing my research on pavement overlay.

I want to model a three layer pavement in ANSYS and apply moving load. There will beinterface between the layers. How can I apply the load? If I marge and compress after meshing; is this the correct way to do that?

Thanks and regards

Fatigue and Fracture

Hi Every one

Greetings!!!

I am a new entrant to this site. This site seems to be very good towards technical aspect.

First of all I would like to introduce myself. I am a Ph.D student working in the area of fatigue.

- Is there anyone to support and share the knowledge in the domain of fatigue?

- Can anyone guide towards the websites that provides very good information about fatigue and related literatures.

Thanks and Regards

ABAQUS_UMAT_STATEV

Dear all,

do you know does any entry stored is STATEV, used in UMAT subroutine,
should remain unchanged for the next increment for the case of finite
deformation?

I know that STRESS and STRAN will be rotated by ABAQUS but what about the STATEV?

I want to protect STATEV from any rotation by ABAQUS in order to rotate
it in UMAT by my rotation matrix but I am experiencing that it is
different value at the beginning of new increment in comparison the one
as output from previous increment.

Thanks in advance,

Marina.

Hang glider manufacturers supply flying cable sets; how might pilots inspect the condition of those cables?

Model of Pavement for moving load

I want to model a pavemnt of three layer and apply moving loads on it by ANSYS. There will be interface between the layers. How can I apply the load? If I merge and compress all after meshing; Is it the correct way to do that?

In the classical Euler buckling problem, the critical buckling load can be increased by a factor of four if the first mode is suppressed by placing an additional simple support at the mid-point.

my problem is simulation of axisymmetric cold extrusion die. the die is conical, i have to determine die pressure, ram force and temprature in billet as well in die, plz see attached file and see simulation figure, my problem is same as in file,i have facing interaction problem in abaqus while solving this problem. plz help me

Data transfer

Hi friends,

I need to transfer stiffness and mass matrices from ABAQUS to Matlab. ABAQUS does generate matrices but those can be re-used by ABAQUS only. Is there a way to use these matrices in matlab. I know about SDT toolbox for matlab and I-MAT but they are costly.
