How does tensile strength of natural plants fibers affects the durability of rope? 


Best insight from top research papers

The tensile strength of natural plant fibers significantly impacts the durability of ropes. Research indicates that fibers like sisal and coir exhibit high potential for various functions due to their resilience against degradation in soil. Conversely, banana fibers are prone to significant degradation under aging and soil conditions, making them less suitable for geotechnical applications. Enhancing the durability of natural fibers, such as jute, can be achieved through unique treatments like alkali-activated binder (AAB) coatings, which improve strength and resistance to different chemicals. The mechanical performance of fibers, like curaua, with high tensile strength and Young’s modulus, directly correlates with the durability and overall strength of the ropes they are used in.

Why the displacement amplitude decrease with increasing the frequency of cyclic applied loading?
5 answers
The displacement amplitude decreases with increasing frequency of cyclic applied loading due to several interrelated factors observed across different materials and conditions. Firstly, as the frequency of cyclic loading increases, there is a significant influence on the mechanical behavior of materials, including the reduction in peak shear stress and volumetric strain, which indirectly affects the displacement amplitude. This phenomenon is observed in soft synthetic rock joints, where higher load frequencies lead to greater reductions in peak shear stress compared to lower frequencies under cyclic movements. Similarly, in granular soil subjected to high-frequency loading, reductions in axial stress and volumetric strain were noted, indicating that higher frequencies can diminish displacement amplitudes. Moreover, the fatigue behavior of materials under cyclic loading also plays a crucial role. For instance, in sandstone specimens, the relationship between the number of cycles and residual strain suggests that higher frequencies lead to a more rapid transition to the accelerated failure stage, which could limit the overall displacement amplitude due to premature material failure. The inclusion of fibers in sandy soil reinforced with polypropylene and sisal fibers showed that higher frequencies lead to an increase in stiffness and a decrease in accumulated permanent axial strain, further supporting the reduction in displacement amplitude with increased frequency. The effect of loading frequency on liquefaction resistance in soils also provides insights. Higher frequencies increase the liquefaction resistance of sand, suggesting that the soil structure becomes more resistant to deformation, thereby reducing displacement amplitude. This is consistent with findings from dual-frequency loading modes on steel samples, where the imposition of a high-frequency component on a main low-cycle loading process significantly decreases cyclic durability, implying a reduction in displacement amplitude under higher frequencies. Experimental observations in cyclic load testing on modules and porous rocks under cyclic compressive tests further corroborate these findings. Increasing the loading frequency was found to reduce maximum power degradation in modules, suggesting less displacement under higher frequencies. In porous coal, higher loading frequencies delayed the damage time and required higher levels of peak cyclic stress amplitude for damage initiation, indicating a reduction in displacement amplitude with increased frequency. Lastly, the utility of high-frequency testing (HFT) for accelerated fatigue testing underscores the principle that higher frequencies can simulate the cumulative effects of fatigue more rapidly, suggesting a more efficient reach to failure or deformation limits, which aligns with the observed decrease in displacement amplitude with increased loading frequency. Collectively, these studies demonstrate that the displacement amplitude decreases with increasing frequency of cyclic applied loading due to the combined effects of reduced peak stress, increased material stiffness, accelerated transition to failure, and enhanced resistance to deformation under higher frequencies.
