Stress–strain analysis

Strength calculations belong to the branch of statics (within the technical mechanics ) and are

• Simple test specimens (eg, rods ),
• Beams,
• Beam structures,
• Trusses,
• Plates,
• Membranes but also
• Complex mechanical structures

Performed.

Strength calculations to help identify strong and weak stressed parts of a structure and thus lead to the optimization of components. They also serve as a computational proof of the safety of a structure. As a method for strength calculations are:

• Graphical methods (eg Seileckverfahren, Cremonaplan )
• Analytical approach (eg Bernoulli beam, Knight cal section method )
• Numerical methods (eg finite element method (FEM) )

Strength calculations are concrete applications of the strength of materials.
