What is Mainly Considered When Calculating Bolted Joint Analysis


Bolted Joint Analysis is a statistical technique applied in various engineering fields such as structural analysis and ergonomics. It is used to analyze the performance of any joint by calculating its life expectancy. This blog post will discuss the factors that affect the bolted joint analysis.

Degree of Material Shrinkage

The degree of material shrinkage depends on the joint. In the case of a bolted joint, the amount of energy absorbed by the bolt and the bolt hole is measured. This method makes it possible to calculate the life expectancy for different types of joints based on their properties.

Bolt Material

The type of material used in bolts also affects its performance. For example, an aluminum bolt that corrodes when exposed to water will lose its strength over time. Therefore, it will not be able to sustain the load placed on it, and hence its life expectancy will decrease over time.

Bolt Hole

The size and shape (or geometry) of a bolt hole also affect its performance and life expectancy. For example, if a bolt has ample space between itself and another object, it will have less friction between them, thus increasing its life expectancy compared to other joints where there is close contact between them.

Bolt Size and Length

The type of bolts used also depends on the size and length of the bolt. If a bolt has a large cross-sectional area, it will have greater strength and durability than a small-sized bolt. For example, in case of a safety bolt with a cross-sectional area of 0.75 mm2 will have higher strength and durability than an aluminum alloy bolt with a cross-sectional area of 0.5 mm2.
