Abaqus - line load on channel beam applied outside of a beam (in shear center)

Submitted by Dzonni on Mon, 04/25/2016 - 21:18

Hello, everybody. I'm having a problem regarding the application of a line load beyond the contours of a channel tube made out of shell elements. I am trying to perform lateral torsional buckling analysis and the load needs to act in shear center. Does anybody have a solution for this?

A recently published paper "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

Fracto-emission in lanthanum-based metallic glass microwires under quasi-static tensile loading

Fracture mechanics; non-linear stress-strain behavior; metallic glass; microwire; in situ SEM testing; nanomechanics; fracto-emission

Plastic deformation in metallic glasses is highly localized and often associated with shear banding, which may cause momentary release of heat upon fracture. Here, we report an explosive fracture phenomenon associated with momentary (∼10 ms) light emission (flash) in Lanthanum-based (LaAlNi) metallic glass microwires (dia. ∼50 μm) under quasi-static tensile loading.

ABAQUS

Hi everyone,

I am working on ABAQUS to simulate Pipeline Inspection Gauge (PIG) movement in a pipeline via CEL technique. I am unable to find how to calculate Pressure Difference in the pipeline using Abaqus.

If anyone of you can guide me through it.

Regards,
