convergence difficulty due to the stiffness degradation in Abaqus

Submitted by morteza roostaei on

Hello everybody

I am simulating hydraulic fracturing operation with Abaqus. I have used cohesive elements and also utilized viscous regularization to cope with convergence difficulty. However, the problem still persists. Should I stick to regularization technique or should I write a user subroutine that will allow more flexibility. 

  Thank you

Fracture of electrodes in lithium-ion batteries caused by fast charging

Submitted by Kejie Zhao on

During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other.  This extraction-insertion reaction causes the electrodes to deform.  An electrode is often composed of small active particles in a matrix.  If the battery is charged at a rate faster than lithium can homogenize in an active particle by diffusion, the inhomogeneous distribution of lithium results in stresses that may cause the particle to fracture.  The distributions of lithium and stress in a LiCoO2 particle are calculated.  The e

Faculty Positions at the University of Illinois

Submitted by Harley T. Johnson on

The Department of Mechanical Science and Engineering at the University of Illinois, Urbana-Champaign is actively seeking candidates for faculty positions in all areas of mechanical science and engineering. We especially seek candidates whose research and teaching interests are in the areas of energy, manufacturing, and biomedicine.  However, the innovative nature of the candidate’s research and the candidate’s potential for leadership are more important than specific research area.

Re-assessing ageing pipeline infrastructure to ensure safety, integrity and reliability

Submitted by Henry Tan on
DISCUSSION THEMES 
  • Assessing the potential of ageing infrastructure to provide the same level of service as newly constructed facilities
  • Identifying the key threats to the integrity of a pipeline in later life
  • New solutions for old pipelines: revealing how new technologies can
    help ensure reliability of older infrastructure and assessing the
    future outlook for mature pipes
  • Taking the necessary steps to make sure that older pipelines are operated within regulatory requirements
