When selecting a fastener, its rated static load capacity must exceed the anticipated static load by a considerable margin to account for manufacturing tolerances and unforeseen stresses. Failure to account for static load may result in deformation or fracture of the fastener. For example, using a fastener rated for 50 lbs to retain a 60 lb object constitutes a hazardous misapplication.
-
Dynamic Load Implications
Dynamic loads involve forces that vary in magnitude or direction over time. These loads are typically associated with moving parts, vibrations, or impacts. Fasteners subjected to dynamic loads experience fatigue, a progressive weakening of the material that can lead to sudden failure. The fastener’s fatigue strength, a material property indicating its resistance to dynamic loading, must be carefully considered. Components encountering repetitive impacts or cyclical stress require fasteners specifically designed for dynamic applications to prevent fatigue-induced failures.
-
Shock Load and Impact Resistance
Shock loads represent sudden, intense forces applied over a short duration. Examples include impacts from collisions or the sudden activation of a high-torque motor. Fasteners intended for applications involving shock loads must possess high impact resistance to prevent brittle fracture. Material selection plays a critical role in achieving impact resistance; materials with high ductility are preferred as they can deform under stress rather than fracturing. Fasteners in machinery subjected to sudden stops or starts are prime candidates for shock load considerations.
-
Environmental Influence on Load Capacity
