Stiffness and Buckling

Industry relevance

The buckling margin is one of the fundamental margins of safety. The buckling is a concern not just for structural elements in compression, the shafts subjected to the shock loading and thermal stresses. The buckling margin also must be traded with vibration and deflection requirements as these also depend on the stiffness. Understanding joint stiffness is key to ensuring integrity and for calculations of bolt load in situations such as external loading, pre-loading ( including unconfined gasket joints), thermal loading etc. Concept of strain energy is a concept used for static trimming of components, to analyze the indeterminant structures and even to understand and predict fracture mechanics.

Example : Joint analysis for various material combinations.
