Classical solution methods in fast Fourier transform-based computational micromechanics operate on, either, compatible strain fields or equilibrated stress fields. By contrast, polarization schemes are primal-dual whose iterates neither nor equilibrated. Recently, it was demonstrated that may outperform the classical methods. Unfortunately, their power critically depends on a judicious choice o...

Abstract A micromechanical model of cross-over fiber bridging is developed for the prediction macroscopic mixed-mode laws (traction-separation laws). The based on non-linear beam theory and takes into account debonding between matrix as well buckling fibers in compression. Further, it shown how failure can be taken through a Weibull distributed strain. Predictions made by proposed are compared ...

This paper presents a new structural approach for diagnosing board interconnects using boundary-scan. While existing diagnosis approaches assume only wired-AND or wired-OR bridging fault model, we consider a more complex bridging short fault model in CMOS circuit environment. The diagnostic test set is generated based on graph theoretic technique and the adjacency fault model is adopted. Both o...

This paper presents accurate fault models, an accurate fault simulation technique, and a new fault coverage metric for resistive bridging faults in gate level combinational circuits at nominal and reduced power supply voltages. We demonstrate that some faults have unusual behavior, which has been observed in practice. On the ISCAS85 benchmark circuits we show that a zero-ohm bridge fault model ...

In this paper, recent work on the modeling for predicting the e€ective thermal and mechanical properties of the ceramic breeder blanket particle bed materials is presented. The model is based on the micromechanics displacement method in conjunction with an iterative process of the successive releasing of ®xing vectors. It serves as an useful tool to study the blanket thermomechanical state unde...
