(2008-08-26)Department: Civil EngineeringFracture and failure mechanics of advanced materials and structures with interfaces was investigated both experimentally and numerically. Dynamic fracture mechanics was used to model the phenomena when a main crack was ...
-
(2004-04-09)Department: Civil EngineeringIn a traffic network users can be classified into various classes based on behavioral rules and the type of information accessible to them. However many existing models assume that the users who belong to these classes are ...
-
(2016-08-16)Department: Civil EngineeringThe degradation of cementitious materials typically begins on the nanoscale and progressively worsens to the macroscale, therefore, carbon nanofibers (CNFs) are excellent candidates for reinforcement of cementitious materials ...
-
(2010-07-13)Department: Civil EngineeringThis study is concerned with the accurate prediction of response of structural components under mechanical loads in the presence of various types of irregularities in homogeneous as well as inhomogeneous systems like ...
-
(2008-08-03)Department: Civil EngineeringAn efficient response surface construction method for fatigue life prediction is investigated in this study, based on the Gaussian process (GP) modeling approach. The model is applied to fatigue crack growth analysis, in ...
