That the material has been weakened from stresses, for example bending.
Both Fatigue and Creep are causes of failure of a material at a stress value significantly below the Allowable threshold. They differ from each other in the sense that fatigue is defined as the failure of a material, subjected to multiple loading and unloading cycles, even though, in none of the instances, the applied stress crosses the Allowable stress value. The fatigue life of a material is usually specified in # of loading/unloading cycles it can undergo, without failing. The fatigue life decreases as the applied stress approaches the Allowable Stress. CREEP, on the other hand, is time related failure of a material. Creep, explains that a material subjected to a certain applied stress will continue to deform at that constant stress value. Hence, creep results in an increase in strain value while the stress is constant, until it causes the failure of the subject material. CREEP tends to increase with the temperature of the specimen
Fatigue strength is the maximum stress that a material can withstand for a specified number of loading cycles before failure occurs. It is an important property in materials science and engineering as it determines the durability of a material under cyclic loading conditions.
Convenient graphical representation of various combinations of mean and alternating stress in relation to criteria both for yielding and for various fatigue lives. Horizontal axis correspond to mean stress. When y=0 it means static loading. Yield and ultimate strength are plotted in x-axis. Vertical axis corresponds to alternating load. When x=0 it means fully reversible
The three forms of fatigue are physical fatigue, mental fatigue, and emotional fatigue. Physical fatigue is the tiredness of the body, mental fatigue affects the mind's ability to focus and make decisions, and emotional fatigue pertains to feeling drained of emotional energy.
Flexible material refers to a substance or material that can bend, stretch, or be reshaped without breaking. Examples include rubber, certain plastics, and fabrics that can easily be twisted or folded. Flexible materials are often used in clothing, packaging, and electronics to provide pliability and adaptability.
description of fatigue and how it can be controlled
Having fatigue doesn't mean you have a STD.

Bending fatigue is the tendency of a material to break. This is usually applicable to metals after repeated stress is applied.

Yes it will bring down the fatigue life and the material will not endure at any point. Degrading nature of fatigue loading on the materials is compounded by the corrosion interaction. Synergistic damage - The damage will be more than the addition of damages due to corrosion and fatigue loading. The formation of intrusion and extrusion due to fatigue loading leads to the notches. The corrosion media will enter the notches and forms oxide with the base metal and it will be passive to further corrosion. But the fatigue loading will disturb the passive layer and facilitate the media to corrode the fresh material. Hence it will drastically decrease the fatigue life of the material.

Fatigue in polymers is the weakening and eventual failure of the material under repeated or cyclic loading, even if the stress levels are below the material's ultimate strength. This can lead to cracks, deformation, and eventual fracture over time. Fatigue properties are important to consider in designing polymer components for long-term durability.
