  2. Torsion spring - Wikipedia

    en.wikipedia.org/wiki/Torsion_spring

    The force of the spring reverses the direction of rotation, so the wheel oscillates back and forth, driven at the top by the clock's gears. Torsion springs consisting of twisted ropes or sinew, were used to store potential energy to power several types of ancient weapons; including the Greek ballista and the Roman scorpio and catapults like the ...

  3. List of finite element software packages - Wikipedia

    en.wikipedia.org/wiki/List_of_finite_element...

    A generic finite element library written in C++ with interfaces for Python, Matlab and Scilab. It focuses on modeling of contact mechanics and discontinuities (e.g. cracks). Yves Renard, Julien Pommier: 5.4.2: 2022-07: LGPL: Free: Unix, Mac OS X, Windows: Hermes Project: Modular C/C++ library for rapid development of space- and space-time ...

  4. Langevin dynamics - Wikipedia

    en.wikipedia.org/wiki/Langevin_dynamics

    The Langevin equation can be generalized to rotational dynamics of molecules, Brownian particles, etc. A standard (according to NIST [ 5 ] ) way to do it is to leverage a quaternion -based description of the stochastic rotational motion.

  5. Mass-spring-damper model - Wikipedia

    en.wikipedia.org/wiki/Mass-spring-damper_model

    The mass-spring-damper model consists of discrete mass nodes distributed throughout an object and interconnected via a network of springs and dampers. This model is well-suited for modelling object with complex material properties such as nonlinearity and viscoelasticity .

  6. OpenSees - Wikipedia

    en.wikipedia.org/wiki/OpenSees

    OpenSees allows users to create finite element applications for simulating the response of structural and geotechnical systems subjected to earthquakes. This framework was developed by Frank McKenna and Gregory L. Fenves with significant contributions from Michael H. Scott, Terje Haukaas, Armen Der Kiureghian, Remo M. de Souza, Filip C ...

  7. Rotational–vibrational coupling - Wikipedia

    en.wikipedia.org/wiki/Rotational–vibrational...

    In the absence of the spring, the particles would fly apart. However, the force exerted by the extended spring pulls the particles onto a periodic, oscillatory path. In physics, rotational–vibrational coupling [1] occurs when the rotation frequency of a system is close to or identical to a natural frequency of internal vibration.

  8. Quaternions and spatial rotation - Wikipedia

    en.wikipedia.org/wiki/Quaternions_and_spatial...

    3D visualization of a sphere and a rotation about an Euler axis (^) by an angle of In 3-dimensional space, according to Euler's rotation theorem, any rotation or sequence of rotations of a rigid body or coordinate system about a fixed point is equivalent to a single rotation by a given angle about a fixed axis (called the Euler axis) that runs through the fixed point. [6]

  9. Euler–Bernoulli beam theory - Wikipedia

    en.wikipedia.org/wiki/Euler–Bernoulli_beam_theory

    The curve () describes the deflection of the beam in the direction at some position (recall that the beam is modeled as a one-dimensional object). is a distributed load, in other words a force per unit length (analogous to pressure being a force per area); it may be a function of , , or other variables.
