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.
