The fracture stress, Young’s modulus and the work of rupture (Wr) for the p-Pep/Cu2+ hydrogel were significantly higher than those of the PAM and p-Pep hydrogels (Fig. 4a and Supplementary Table 1). The Young’s modulus of the PAM, p-Pep and p-Pep/Cu2+ hydrogels were 13.2, ...
(a) Nominal strength smax, (b) stretch at rupture λmax, (c) true strength σmax, and (d) work of fracture Wf are plotted as functions of F with lines of constant C. All properties are measured at the point of rupture in the monotonic stress-stretch curves. smax increases with increa...

For specimens that experienced fatigue failure, side-surface observations were performed at a certain distance from the fracture surface to mitigate the influence of the main crack on fatigue damage. This observation area showed no significant plastic deformation. For specimens that did not fail even ...
With this method, it is possible to calculate the fatigue life as well the position of the fatigue fracture plane. The Findley’s critical plane stress [55] value is defined as follows: 𝑆𝐹=max[𝜏𝑎,𝐶𝑃(𝜃𝐹)+𝑘𝐹𝜎𝑚𝑎𝑥,𝐶𝑃)]SF=maxτa,CPθF+kFσmax,...

Since the macroscopic stress-strain response in all cases was observed to be linear elastic, linear elastic fracture mechanics (LEFM) analyses were carried out to determine the crack growth curves of the material assuming that crack initiation from a micropore (a sub o = 40 microns) occurs very...
这个标准提供了通过线性弹性断裂力学(LEFM)方法来测定塑料材料在拉伸-拉伸疲劳条件下的裂纹扩展速率的方法。 LEFM方法是一种通过测定试样在受到周期性拉伸载荷时的裂纹扩展情况来评估材料耐久性的方法。这种方法基于这样一个原理:当材料受到周期性拉伸载荷时,裂纹会以特定的速度扩展,这个速度与材料的性质(如弹性模量、...
Owing to their excellent biocompatibility and capability of large deformation, hydrogels have attracted extensive attention for promising applications. Whe
