Here, harnessing the mesh-to-graph mapping, we propose a graph-based ML general method to predict deformed shapes, stress and strain fields in material and structural systems. To demonstrate the flexibility and generality of the proposed approach, we focus on three different material systems undergo...
load against extention graph应该就是典型的金属试样拉伸曲线图；而stress against strain graph分为名义应力应变曲线（形状与load against extention graph一样）和真实应力应变曲线（即考虑拉伸过程中达到塑性变形之后的颈缩效应导致的试样截面缩小，可以由名义应力应变曲线转换，具体参见相关资料。）
The von Mises criterion states that yielding occurs when the shear strain energy reaches a critical value. For a general case with three principal stresses: (4.22)(σ1−σ2)2+(σ2−σ3)2+(σ3−σ1)2=constant The constant is found by considering the uniaxial case (σ1=σ1, σ2...
The stress-strain curve provides design engineers with a long list of important parameters needed for application design. A stress-strain graph gives us many mechanical properties such as strength, toughness, elasticity, yield point, strain energy, resilience, and elongation during load. It also help...
The Burgers model is accepted as the general model of these clayey soils. By means of orthogonal tests and variance analyses, it is found that the effect of soil conditions (mechanical composition, water content, bulk density) on Theological parameters G_0, G,畏_0, and 畏 is particularly ...

Graph, mean ± SEM, unpaired two-tailed t-test, n = 3. d, e Viability of iPSC-derived neurons cultured for 24 h with Vehicle (V) or PU (0.5 µM PU-AD) (d) or for 72 h with concentrations of PU-AD from 0 to 100 µM (e). Graph, mean ± SEM,...
2b). Importantly, the severe growth phenotype was absent in a vector control strain overexpressing lon alone (Fig. 2e) and to a milder extent when co-overexpressing F-larA in combination with lonTRAP (Fig. 2f). These data suggest that the levels of proteolytically active Lon are rate-...
The increased transcription of fixN1 in particular had also been reported in a strain of S. medicae incubated in batch at low pH77. The present results would indicate that the cellular role of certain of the fix genes exceeds their sole participation in nitro- gen fixation during late ...
