where Mkk represents the trace components of the moment tensor,  and  are Lame constants. These results imply that the damage evolution and the accumulation of relative crack volume are also estimated from the moment tensor analysis. From moment tensors determined in bending tests of concrete specimens with a notch [Ohtsu & Ohtsuka 1998], the damage and the accumulation of crack volume were e...

A novel ultra-wideband (UWB) monopole antenna with triple band-notched functions is presented. A pair of folded multiplemode resonators (MMR) symmetrically coupled to the feed line are utilized to generate triple notched bands for WiMAX, WLAN and downlinks of X-band satellite communication, respectively. The centre frequencies and band gaps between them can be tuned by varying the length and wi...

Many bridges built during the colonial times in Australia have timber girders as load transferring elements and they are still service with increased traffic loads consistent deterioration. Most of those notched at ends for better seating arrangement. Therefore, it is necessary to quantify strength characteristics order ensure structural safety make intervention extend their lives. Hence experi...

Abstract The lifetime of most metals is limited by cyclic loads, ending in fatigue failure. progressive growth cracks ends up catastrophic An advanced method presented for the determination crack on microscale using a nanoindenter, which allows characterization > 10,000 loading cycles. It uses focused ion beam fabricated notched microcantilevers. has been validated bending metallic glass and...

this paper presents an e-ring shaped printed monopole antenna for uwb applications with dual notched bands performance. in order to generate single frequency band notch function, we applied a u-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an e-ring shaped radiating patch created and a dual band-notch function can be achieved. the measured bandwidth of th...

This paper investigates the effects of support friction on mixed-mode I/II fracture behavior compacted clay using notched deep beam (NDB) specimens under symmetric fixed support. Numerical models 330 NDB were established considering crack inclination angle, length, span, and coefficient, normalized parameters (YI, YII, T*) calibrated. The numerical results showed that values YI, T* decreased at...

Intensity coding mechanisms are explored in a paradigm involving both forward and simultaneous masking. For intensity discrimination of 1000-Hz pure tone in quiet, a near-miss to Weber's law is observed. However, as more stimulus components are added to this relatively simple experiment, interactions among components produce a more complex pattern of results. An intense forward masker, while no...

A compact rectangular slot antenna with single wide band-notched characteristics is proposed. This co-planar waveguide (CPW) fed antenna is suitable for ultra wide band (UWB), X-, Kuand K-band applications. The patch of the antenna is a modified rectangular slot with T-stub structure in an elliptical slot etched in the radiating patch. This T-stub structure creates wide band notched at WLAN and...
