没有理由进行竞争。我提供了足够的材料进行比较。在我的论文“Approach”中，
- p.2628我提出了一个与物质无关的固体状态方程，我用布里奇曼的数据证明了它是有效的，至少对碱是有效的。
- on p.2636我给出了一个计算实例来说明，对于受纯剪切作用的各向同性材料，其体积应保持恒定。
- on p.2644-45我给出了一个计算的例子来表明，对于受简单剪切作用的各向同性材料，体积应该膨胀(Poynting效应)。
-从理论的系统分析可以预测，在纯剪切或简单剪切中，剪胀应该是各向异性材料的共同效应。
- on p.2644我预测了单剪的特征方向和运动学，并与图13 ff中的实际情况进行了比较。
- on p.2647 Fig.15 I compare my prediction with the observed orientation of joints in shear zone rocks.
- on p.2648 Fig.16 I compare my predictions with the observed max stress orientation along the San Andreas Fault. The orientation expected by workers on this fault is at 45°, observed is ca.80°, my prediction is 80°, with correct asymmetry relative to sense of shear. (Research on why the orientation is nearly vertically on the fault is a very active research subject, google for 'SAFOD-project'. The high angle is not a special Californian fault feature. The same orientation
is found along the North Anatolian Fault, the Kenai Fault in Alaska, and a large fault in Japan for which I have seen the data.)
- on p.2648, Chapter 8, I derive the work done in pure and simple shear, elastic and plastic deformation. The prediction is that in the elastic field, simple shear should cost a little more than pure shear per chosen unit strain, whereas in the plastic field simple shear should cost substantially less than pure shear per chosen unit strain. The observed data are available at
http://www.elastic-plastic.de/experimentaldata.pdf.
Should Chad believe that these data are insufficient, he is invited to search for better ones. I am confident that the pattern will persist.
- on p.2652, Fig.17, I predict the orientation of cracks in solids in 3D, to the best of my knowledge absolutely correct. (Seen enough shear zones in my life.)
- on p.2653 I compare the calculated orientation with observed cracks in sea ice. Given some natural variation, the predictions are right on the mark.
- on p.2653 Fig.18, and on p.2654 in the text, I show that upon irreversible relaxation of the elastically loaded state, an unbalanced rotational momentum is released which will actually cause external body rotatation about a rotational axis close to the direction perpendicular to the shear plane. This unbalanced momentum is a prime candidate for the origin of turbulence in fluid flow, plus for a few other phenomena, such as sheath folds, which may not be known to engineers, but are well known among structural geologists working in large shear zones.
- on p.2659 I offer the interpretation that the reduced density in Prandtl boundary layers is due to the Poynting effect.
- on p.2662 ff (Chapter 12) I give a calculated example for the distribution of deformation in a technical experiment, namely a block with free lateral surfaces which is loaded vertically, as a function of shape (the vertical dimension varies from one unit to 30 units).
Altogether, there cannot be better predictions, excuse the satisfaction. Thus there should be enough meat to sink his teath in even for Chad Landis.
The critical deformation state to test the conventional theory is simple shear. I am fully confident that for sufficiently high symmetry conditions (orthorhombic or higher) the conventional theory will not fail obviously. It was the inconsistencies between the predictions and observations for simple shear – in the elastic (Poynting), plastic (SC-fabric, microfabric, energetic) and viscous (turbulence) field – that made me study continuum mechanics in the first place.
One can easily arrive at right results for the wrong reasons. But right answers don't matter. What matters is to ask the right questions, then the right answers will come by themselves.

尊敬的先生，如果我在它的两端之一施加一个任意的力，同样的力会在无穷远的另一端起作用吗??这里横梁是水平的，我在横梁的方向上施加力。
