Mechanics of solid bodies

The mechanics of solid bodies is a fundamental branch of classical mechanics , continuum mechanics and experimental physics . It deals with the movement of solids under the influence of external forces . A distinction must be made between:

• the ideal case of a non-deformable, completely rigid body . For the investigation, these are put together mathematically from mass points ; the movements examined are mainly translational movements and rotations .
• the real, elastically or plastically deformable solids. This is where the analysis of vibrations , deflections and deformations comes in.

The mechanics of solid bodies, the counterpart of which is the mechanics of fluids , represents the general basis of physics and therefore almost always forms the beginning of physical study books and lecture series.

Mechanics of Solid Bodies is accordingly the title of several textbooks that have been published since the beginning of the 20th century. The best-known authors include Heinz Parkus ( TU Vienna ) and Siegfried Heitz ( University of Bonn ).

Most textbooks divide the subject into the areas

• Statics (including reference and force systems, mass geometry, equilibrium, rod-shaped solids, trusses, laws of friction),
• Strength theory (tensile and bending tests, stress distribution, bending line, torsion; elasticity theory, plasticity, rheology, hardness, density, structural mechanics, etc.),
• Kinematics and dynamics (angle or velocity vector, acceleration, jerk, moments, etc., basic kinetic equation, center of gravity and twist theorem, Kepler's and fall laws, Euler's gyroscopic theory, etc .; gravitation, work, power, kinetic energy, vibrations, impact processes).
