Dear Colleague,

we would like to inform you that the EUROMECH Colloquium 575 on “Contact Mechanics and Coupled Problems in Surface Phenomena” will take place in the IMT Institute for Advanced Studies Lucca (Lucca, Italy) from March 30, 2015 to April 2, 2015.

Abaqus warning of Negative Eigen value

Submitted by mrashidzafar on Tue, 09/16/2014 - 11:56

I am doing a FE formulation of surface elasticity. I wrote UEL for surface elements in addition to abaqus volume elements. But surfaces may have negative stiffness (constitutive relation as per Morton Gurtin's formulation). So as a result I am getting a warning of "Negative eigen values". Can any body tell me how abaqus is solving for this system matrix (with few negative eigen values) in Static General method?

Impact analysis

There is still time to apply the 5-year post-doctoral position at the University of Southampton. We are looking for a talented young researcher to join a group working on the definition of the next generation of high strain rate tests based on ultra-high speed deformation imaging and inverse identification (PhotoDyn project). Please apply online before September 30th.
