仅在一定范围内的应力和应变。如果一种材料的变形超过了它的弹性极限，那么应力-应变比就会改变，当释放张力时，拉伸不再反转，最终达到断点。作者在他们的讨论中错误地指出，较大的动脉瘤中增加的壁张力将“抵抗进一步的扩张”。相反，张力是一种倾向于扩张并最终破裂动脉瘤的力量。不同健康和疾病受试者的活体主动脉壁的力学特性显然不是简单的。作者对我们的理解做出了有益的贡献，但不需要通过混淆与解释他们的数据相关的物理学的更简单的方面来使这个主题看起来比它更复杂。
stress and strain only within certain limits. If a material is deformed beyond its elastic limit the stress-strain ratio changes, the stretching is no longer reversed on releasing the tension, and breaking-point is eventually reached. The authors wrongly state in their discussion that the increased wall tension in larger aneurysms would ‘resist further distension’. On the contrary, tension is the force that tends to distend and ultimately rupture the aneurysm. The mechanical properties of the living aortic wall in different healthy and diseased subjects are clearly not simple. The authors make a useful contribution to our understanding but need not make the subject appear more complex than it is by confusing the simpler aspects of physics relevant to interpretation of their data.
