Fault, crushed zone, and other unfavorable geology may frequently appear in the construction of tunnels, so it is course necessary to study on dynamic properties tunnels crossing rock fracture zone. Taking tunnel faults as object, this paper discussed constitutive relation satisfied by structures researched loading features failure characteristics different faults. It shows that: (1) areas with...

Internal bond strength testing is a widely used approach for testing quality traits of wood based panels. Generally, failure of internal bond specimens is due to adhesion and/or wood failure in the specimen. It has been reported that a composite product with a large variation in the vertical density profile fails in the center part of the board which is either the middle of the core layer or th...

[1] The Kaoiki Seismic Zone at Mauna Loa’s east flank is the locus of some of the largest earthquakes on Hawaii. In this paper we examine the link of those earthquakes to volcanic activity at Mauna Loa. We calculate the changes of Coulomb failure stress along the Kaoiki faults for typical volcanic events at Mauna Loa volcano. We simulate the dislocation associated with the 1950 eruption at the ...

I thankLockner et al. [this issue], hereafter referred to as LBS, for their interest in this work. LBS suggest that I [Marone, 1995] misunderstood their analysis and that their proposed empirical relation is indeed valid. I do not agree. I do not deny that LBS have established some form of empirical relationship, only the specific form of the relation and its theoretical basis are at issue. The...

BACKGROUND Treatment failure defined as progression of disease after initiation of ART or when the anti-HIV medications can't control the infection. One of the major concerns over the rapid scaling up of ART is the emergence and transmission of HIV drug resistant strains at the population level due to treatment failure. This could lead to the failure of basic ART programs. Thus this study aimed...
