Bending of cables : a stick-slip model

Submitted by Alain Cardou on Sat, 08/10/2013 - 20:10

Bending of cables and, for that matter, of any helical strand system (such as overhead electrical conductors) is a challenging solid mechanics problem, with geometry and multibody frictional contact aspects. As seen in several recent papers, one workable approach is based on Coulomb’s laws of friction. An earlier contribution by Lehanneur (1949), published in French, has generally been ignored. The attached report presents a translation into English (including a presentation) of this most interesting work.

Poroelastic soil Material in Abaqus

Hello everyone,

I need an urgent help. I have no idea how to define two phase poroelastic soil in abaqus. Water and soil should be treated as two different materials rather than a single material. And how to define the poroelasticity (saturated soil). Can abaqus perform these analysis.

(1) Coupled quasi-static for saturated soil

(2) Coupled dynamic for saturated soil (the UEL/UMAT) -- this is
reported as a UMAT.

Please help me how to sdo these steps and how to define UEL/UMAT

Regards

Rahul

Split Hopkinson Pressure bar (or Kolsky bar)

Many prior posts asked about manufacturers of Split Hopkinson Pressure Bar equipment. REL Inc in Calumet MI (http://www.relinc.net/products/hopkinson-bar/) designs, builds & installs custom equipment to meet your requirements. We offer a university discount. And, we provide in-house testing; manufacturing of samples, etc. A new offering in this field is our SurePulse software which simplifies the data acquisition effort for Hopkinson bar testing.
