In order to analyze the propagation of shocks due to hypervelocity impact of micrometeoroids and space debris on spacecrafts, it was necessary to analyze the high-frequency shock-propagation-dynamic on complex structures representative of real spacecraft structure.
Three numerical examples are presented to show the capability of this method in modelling wave propagation and dynamic fracture problems.
This paper investigates on the uncertainty propagation in dynamic characteristics (such as natural frequencies, frequency response function and mode shapes) of laminated composite plates by using fuzzy approach.
The proposed approach is enticing from an engineering perspective aimed at predicting the onset and propagation of dynamic shear localization in actual structures.
The propagation of dynamic ripples induced by a C60 molecule is observed in pristine and defective graphene by molecular dynamics simulations.
A number of strategies are proposed for the approach, including strategies for design variables reduction, variable dependency graph development, constraint propagation, and dynamic verification of a design over an assigned set of attributes (variables).
We show our aspect language offers a concise, practical and adaptable solution for dealing with unanticipated algorithm extension for forward data-flow propagation and dynamic type checking of terms.
It is concluded that current specifications for the splitting test of quasi-fragile materials (concrete, rock, ceramics) should be examined under the light of recent advances in fracture crack propagation and dynamic rupture, properly considering the influence of the not yet clearly defined material properties and geometry of the strip.
These assumptions naturally lead to an elegant empirical Bayes inference procedure that exploits Monte Carlo EM, belief propagation, and dynamic programming.
