The Computing of Intersectant Relations for Its Strength Problem on Damage and Fracture to Materials with Short and Long Crack

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Adopt two types of damage variables, a and D, and make the bidirectional combined coordinate system and the bidirectional curves in the whole process, describing their damage evolutive behaviors on fatigue damage‐fracture to elastic‐plastic steels; communicate the cross‐referencing between their computing models and between describing curves at each ...

Recent Developments in Instantons in Noncommutative ℝ4

Advances in Mathematical Physics, Volume 2010, Issue 1, 2010., 2010
We review recent developments in noncommutative deformations of instantons in ℝ4. In the operator formalism, we study how to make noncommutative instantons by using the ADHM method, and we review the relation between topological charges and noncommutativity. In the ADHM methods, there exist instantons whose commutative limits are singular.
