Quigley Scientific: Tolerance Variation and Affect on Durability Under Random Loading at Elevated Temperature


Tolerance Variation and Affect on Durability Under Random Loading at Elevated Temperature


A stress, fracture and fatigue analysis depending on tolerance variation and stack up analysis of a complex automotive application. The product involved a bolted assembly of stamped metal and composite parts. The fracture and fatigue analysis involved understanding the mechanisms in the fabrication that affected the durability and performance of the assembly. The loadings included random vibration at elevated temperatures as found in the automobile engine compartment.
