Contact dynamics

<p>Contact dynamics deals with the motion of <a href="/facts/Multibody_system/u3yeqc8a">multibody systems</a> subjected to <a href="/facts/Unilateral_contact/PWoXW1g3">unilateral contacts</a> and <a href="/facts/Friction/d0108Rpu">friction</a>. Such systems are omnipresent in many multibody dynamics applications. Consider for example
</p>
<ul><li>Contacts between wheels and ground in <a href="/facts/Vehicle_dynamics/qu2g6Eek">vehicle dynamics</a></li>
<li>Squealing of brakes due to friction induced oscillations</li>
<li>Motion of many particles, spheres which fall in a funnel, mixing processes (granular media)</li>
<li><a href="/facts/Clockwork/ofYRa6kD">Clockworks</a></li>
<li>Walking machines</li>
<li>Arbitrary machines with limit stops, friction.</li>
<li>Anatomic tissues (skin, iris/lens, eyelids/anterior ocular surface, joint cartilages, vascular endothelium/blood cells, muscles/tendons, et cetera)</li></ul>
<p>In the following it is discussed how such mechanical systems with unilateral contacts and friction can be modeled and how the time evolution of such systems can be obtained by <a href="/facts/Numerical_ordinary_differential_equations/rbrYBco3">numerical integration</a>. In addition, some examples are given.
