i need your help. i want to solve the problem of fracture mechanics using ANSYS.
now, i'm trying to solve the problem that is part-through crack in cylinder for stress intensity factor through J-integral. Of course in 3-D.
but, model the cracktip and describe the crack surface is very difficult and complicate.
and i also want to know function of BSPLIN.
The work involves working
independently and collaboratively on: Identifying processing parameters that
will optimize the properties of the bi-metallic joint, developing a material
constitutive model for impact loading conditions, developing an experimentally
validated numerical model the can be used to predict the joint performance
under impact loading conditions, and developing design and processing
guidelines for the bimetallic joints.

Hi everybody!
for plates with constant thickness and two opposite sides simply-supported B.Cs, we can write w(x,y)=f(y)*sin(m.Pi.x) and solving the problem from this viewpoin.
I wonder whether this approach is true for plates with (linearly) variable thickness?
many thanks

Dear all,
I want to do a frequency analysis of a 3d frame which has three beam elements (2 columns and one beam). There are no lumped masses in the model. I want to assign mass to all three elements equal to m per unit length of the members.
When I assigned nonzero density in the beam section definition (equal to m/A, where A is the cross section area),
When I changed from beam elements into frame elements
When I changed from beam of linear geometric order to beam of quadratic geometric order (standard element libraries)
Dear everyone,
Now, I am trying to write Abaqus user defined subroutine(UMAT) for Rousselier damage model, but I don’t know how to define the consistent tangent modulus (the Jacobain) for this model.
Could anyone please give me some information or suggest to me how to determine the equation of this term (Jacobian) ?
Thank you very much indeed
Sutham A.
