Thus, the yield stress at this temperature appears to be substantially higher than the 300 MPa (initial stress in Figure 7a), building up in the specimen during cooling.
Three categories of physiological stress classification were proposed, due to the thermal discomfort for crossbred goats, taking into account the behavior of the PSR in the studied temperature ranges, being classified in thermal comfort, initial stress and full stress.
It could be a strain on a relationship, but sitting by the fire and watching football after a successful morning hunt is a reward that most partners will find worth the initial stress.
Although the idea of being away from your phone might strike the fear of God into many, after the initial stress will come relief as you begin to focus on what's going on around you and not on a screen.
Figuring out how to stop being bullied (e.g., reporting the bullying to a parent or safe adult, learning prosocial skills, increasing self-confidence, etc.) is far more effective than carrying the burden by oneself, which can increase the likelihood of social isolation and aggravation to the initial stress of being bullied.
Figure 7 shows the SEM micrographs of the AQ80M bare alloys with different initial stress. Figures 7(a)-7(d) are the representative pictures of corrosive pits (red arrows) with a load of 0.3-0.75[[sigma].sub.0.2] and tested for 120 h, and Figure 7(e) is tested for 240 h under a load of 0.75[[sigma].sub.0.2].
Nevertheless, for some projects of swelling rock, like slope and protection of mine prop whose initial stress is changed due to the excavation and loading, the stress boundary condition of practical engineering can be better reflected as these projects are simplified as the one-dimensional problem under the unconfined lateral condition.
Three constant loading amplitudes, that is, [F.sub.max] = 17 kN, 18.5 kN, and 20 kN at R = 0.1, are applied to obtain the cyclic cohesive model parameters, where the corresponding initial stress intensity range are [DELTA][K.sub.i] = 54 MPa [m.sup.1/2], [DELTA] [K.sub.i] = 58 MPa [m.sup.1/2], and [DELTA][K.sub.i] = 63 MPa [m.sup.1/2], respectively.
If the ratio of P-wave velocity to wave velocity corresponding to the kth overpressure front at depth "z" is denoted as [f.sub.kz] = ([V.sub.pz]/[V.sub.kz]), then at initial stress levels [f.sub.kz] is equal to one.
The initial internal pressure will change the initial stress state of the pipe.
The placebo group did not show any significant changes in initial stress levels.
The initial stress concentration factor is expected to increases abruptly with combination of bending-torsion & localized stress near crack root tip at surface A as shown in figure3.
