Modelling Ice deformation and fracture in Abaqus

Hello Abaqus Users,

I am new to Abaqus: I am trying to model formation and propagation of fractures in glacial ice (note: ice deformation mainly by plastic flow). I was wondering if anyone has modeled ice as a material exhibiting a nonlinear behavior, or possibly have a user subroutine for ice that I could use. Thanks in advance for any help.

solver for a very hetereogeneous system of equations

Submitted by phunguyen on

Hello everybody,

I am solving a FE problem on a hetereogeneous medium consisting of rigid phase (Young modulus of about 100 000 N/mm2), a softer phase (Young modulus of 20 000 N/mm2) and pore (Young modulus of 1 N/mm2). The reason that I have to mesh the pore is that there are some elements of rigid phase hanging out in the pores. So, if I do not mesh the pore, then my FE matrix is singular.

Hi ,

I am trying to model cooling of molten glass in ABAQUS. Does any one knows how to convert the viscosity data for ABAQUS?

I have viscosity curve against temperature for my glass. In ABAQUS, choosing time based Viscoelastic behaviour, Prony series coefficient needs to input for ABAQUS.

DOes any one knows how can i find theses coefficient from viscosity curves, or any other thing that can be helpfull.

Thanks

Soheil,
