A new parallel sparse direct solver: numerical experiments in large-scale structural mechanics parallel computing

Submitted by saberelarem on

 The main purpose of this work is to present a new parallel direct solver: Dissection solver. It is based on LU
factorization of the sparse matrix of the linear system and allows to
detect automatically and handle properly the zero-energy modes, which
are important when dealing with DDM. A performance evaluation and
comparisons with other direct solvers (MUMPS, DSCPACK) are also given
for both sequential and parallel computations. Results of numerical
experiments with a two-level parallelization of large-scale structural
analysis problems are also presented: FETI is used for the global
problem parallelization and Dissection for the local

Literature on CZM and it's implementation through FEM

Submitted by Anonymous (not verified) on

Can anyone suggest some basic literature on Cohesive Zone Modeling and it's implementation through FEM? Most of the literature, I find, is on traction-separation behaviour and some simulation using a FEM package. I 'm interested to learn it's mathematical formulation and implementation through FEM. Can anyone help me?

SES 2011, Minisymposium on Mechanics of Adhesion

Submitted by Jianliang Xiao on

Adhesion has long been an important issue for mechanics and many other disciplines. Its influence spans macro-, micro-, nano- and molecular scales. When size goes down, adhesion plays a more and more significant role. Many important technologies attribute to adhesion, such as transfer printing for advanced microfabrication,  super adhesives inspired by gecko foot hairs, and self-assembly. Adhesion also has strong implications on the behavior of nanomaterials (such as nanotubes and graphenes) and biological system (such as cells).

Positive definite stress-strain matrix

Dear friends,

 I'm an MSc. student at Bogazici University, Turkiye and I'm working on a thesis project about the failure behaviour of fiber reinforced laminated composite plates under different loading types. The material which we use are AS4 fiber reinforced  prepregs and their mechanical properties are the following:

 

E11 =134,000 MPa

E22 = E33= 9480 MPa

G12 = G13= 5490 MPa

G23 MPa =3272

nu12 = nu13 =0.271

nu23 =0.448 

Gordon conference on the Science of Adhesion

Submitted by Chung-Yuen Hui on

The GRC on Adhesion
Science will be held from July 24-29, 2011, at Bates College, Lewiston,
Maine, USA. TThe goal of this conference is to encourage communication
and discussion of ideas and new unpublished resutls at the very frontier
of adhesion science, by bringing together outstanding internation
scientists from academia, industry and government, while striving to
expand traditional adhesion science into new directions such as cell
adhesion, bio-inpsired adhesives and soft matter physics and
mechanics.   The GRC offer an exciting opportunity for young
investigators to get involved at the frontier of science.   Attendees
will not only be able to discuss the progress of unpublished research
