Ductile Damage Evolution under Triaxial Stress Conditions: Computational and Experimental Evaluations
The continuum mechanic simulation of micro-structural damage process is important in the study of ductile fracture mechanics. In this paper, the continuum damage mechanics model formulation proposed by Lematire has been validated against ductile damage evolution experimentally measured in A533B-C1 steel under stress triaxiality conditions. First, a

متن کاملDynamical Evolution : Spirals and Bars
Non-axisymmetric modes like spirals and bars are the main driver of the evolution of disks, in transferring angular momentum, and allowing mass accretion. This evolution proceeds through self-regulation and feedback mechanisms, such as bar destruction or weakening by a central mass concentration, decoupling of a nuclear bar taking over the gas radial flows and mass accretion, etc.. These intern...
متن کاملError bars in experimental biology
Error bars commonly appear in figures in publications, but experimental biologists are often unsure how they should be used and interpreted. In this article we illustrate some basic features of error bars and explain how they can help communicate data and assist correct interpretation. Error bars may show confidence intervals, standard errors, standard deviations, or other quantities. Different...
متن کاملProbabilistic retrieval: new insights and experimental results
We present new insights on the relations between a recently introduced probabilistic formulation of the content-based retrieval problem and standard solutions. New experimental results are presented, providing evidence that probabilistic retrieval has superior performance. Finally, a unified representation for texture and color is introduced.
