CSAR Seminar
SPEAKER: C. T. Liu, Southern Illinois University at Carbondale
TITLE: Multi-Scale Approach to Investigate the Tensile and Fracture
Behavior in Solid Propellants
DATE: Wednesday, December 7, 2005
TIME: 12:00 Noon
PLACE: 2240 DCL
1304 W. Springfield Ave., Urbana, IL
ABSTRACT
In this talk, the results of recent research in the areas of cumulative
damage and fracture behavior in solid propellants will be presented.
Both mechanical and nondestructive testing techniques were used to
monitor damage initiation and evolution. Multi-scale approaches were
used to investigate the deformation and fracture mechanisms and to
simulate the damage and fracture processes in the material. The
results of the experimental and numerical modeling analyses will be
presented.
