Several new calculating equations on the damage-evolving rate are suggested for describing the elastic-plastic behavior of some materials under un-symmetric cyclic loading. And the estimating formulas are given of the life relative to varied damage value D oi at each loading history. The method is to adopt the ratio of plastic strain range …
After estimating Young's modulus of the intact state from the correlation between AE rate and a damage parameter in each core, the damage levels of …
Second, how does the relative damage rate, for the SPPs and the bulk, compare under different irradiation types. This investigation seeks to understand how the differences in primary interactions of protons and neutrons with a material affect initial irradiation damage, in the hope of informing more robust protocols for the use of protons …
The relative damage rate at the reference location as function of time is plotted in figure 8 left. As. suspected from the stress signals, an important increase of …
Abstract. Materials and Structures (2007) 40:221–227 DOI 10.1617/s11527-006-9133-9 ORIGINAL ARTICLE Relative damage evaluation of concrete in a road bridge by AE rate-process analysis Tetsuya Suzuki · Masayasu Ohtsu · Mitsuhiro Shigeishi Received: 25 October 2005 / Accepted: 7 December 2005 / Published online: 6 July …
Relative damage ratios, defined as the rate of each damage type divided by the total damage rate, were calculated to test our second prediction (P2). Six plots were excluded from statistical analyses because they were partly logged for power lines (three plots in old-growth forests) and Gastrodia elata (a traditional Chinese medicine) planting ...
Serious damage can cause accidents in the unit, threatening the safety of the operators. ... It occurs within the range of 40% to 70% or 30% to 80% of the optimal …
The SW-9 DarkSlayer has 2 modes, the first which has a longer cooldown with more damage while the second mode utilizes quick slashes while releasing a barrage of attacks on every 3rd attack, dealing 50 damage 4 …
The resulting changes in the basal-plane elastic shear moduli of these samples show that the relative damage rate is substantially higher at the higher neutron energies than is predicted by existing models. The results of these experiments have been used to generate a new relative damage function which will allow better projections of …
The relative damage rates in X-PEEM and STXM are compared. The damage chemistry has been studied by comparing the C 1s, N 1s and O1s NEXAFS spectra of the damaged and undamaged materials. Based on these quantitative dose–damage measurements, procedures in X-PEEM and STXM are recommended …
To analyze the occurrence of AE events quantitatively, the rate-process theory was introduced (Ohtsu 1992). Suzuki, one of the co-authors of this article, proposed evaluating concrete damage using ...

Re: May 15 article, "New rate plan satisfies some, angers others." Public Citizen commends the leadership shown by the Austin City Council in taking the reins on the Austin Energy rate case.
Although tissue-level creep strain predicted the amount of collagen denaturation (Fig. 2B), neither parameter was a rate-independent indicator of damage relative to failure or failure itself. RTT fascicles that were cycled at faster strain rates sustained more denaturation as a function of the incremental fatigue level ...
In typhoon risk assessment, we can use the relative damage rate caused by typhoon hazards L ′ and the probability F of its occurrence to classify the levels. As can be seen from Table 5, the highest direct economic loss of typhoons is 0.3718% and the lowest is 0.017%, which is on the interval of [0,0.5%]. The highest proportion of the ...
This work aims at identifying the behavior of polyamide 66 (PA66) under different Relative Humidity (RH) conditions using a phenomenological model that accounts for viscoelastic and viscoplastic rheology coupled to ductile damage. An experimental approach is designed considering different loading conditions, namely: monotonic at …

In terms of the RSM-CQC, the maximum relative errors of RSM-CQC are lower than 0.11%, and the 2-norm relative errors are lower than 0.1%, no matter the expected damage rate or expected life, which can be fully demonstrated that the RSM-CQC has no loss of accuracy compared with the Single Moment method.

In Fig. 5, relative moduli E 0 /E*, vary from 0.48 to 1.25. Relative damages in nine samples are estimated as below 1.0. Though the degree of damage in the concrete samples is not clearly identified by the unconfined compression test in the figure, it is quantitatively estimated, using the relative damage evaluated by AE measurement.
The relative damage accumulation rate in each loading cycle can be considered as a parameter characterizing the contribution of load type to the total damage. The dependences of relative damage rate on the holding time for the penultimate …
The relative damage production rates are in agreement with predictions based on damage energy calculations. 1. Introduction The measurement of damage rates at low tempera- tures using resistivity or other techniques can provide a basis for comparison of total defect production in a variety of irradiation sources. Experiments …

The first factor was spraying concentration (10%, 30% and 50%) and the second factor was interval of spraying (once every 5 days, 10 days and 15 days). The variables observed were absolute damage rate, relative damage rate, plant height, number of leaves and fresh weight of kailan.
These aspects include operational life reduction ratio, rutting rate, linear and nonlinear relative damage concepts. It was concluded that on average real tires with …
Thus the relative damages are quantitatively evaluated from static and dynamic Young's moduli and compared with results of AE rate-process analysis. It is widely reported and realized that durability of concrete decreases due to such effects, as salt and chemical attack, freezing and thawing, and carbon
