Hyperbolic systems of balance laws with stiff source

Journal of Differential Equations, 2023
The author studies hyperbolic systems of balance laws with relaxation terms acting only on some of the components of the state vector whereas the remaining components satisfy conservation laws. In particular, the dissipation induced by the source is only partial, which is the main difficulty in constructing the theory of the Cauchy problem in BV ...

Fault and System Stiffnesses and Stick-Slip Phenomena

pure and applied geophysics, 1978
This paper discusses the influence of system stiffness on the dynamic instability of fault surfaces under laboratory conditions for a number of test modes. In conjunction with shear load stiffness, the normal load stiffness, often neglected, is shown to have a considerable effect on the stick-slip process —its presence or absence and its ...

Assembling the System Stiffness Matrix

2016
Having decomposed the structures into nodes and elements, it is clear that knowing the nodal displacements will give us the internal loads in the elements. The displacements at the closed degrees of freedom are known, but we must still compute the displacements at the open degrees of freedom.

Stiff Systems and Multiple Scales

2012
Most physical or engineering dynamic systems exhibit a mixture of fast and slow variations. Such systems are known as multiple scale systems or stiff systems. Some examples have already been considered. It is relatively rare that the dynamics of a physical system evolve on a single time scale.

Methods for parallel integration of stiff systems of odes

BIT, 1992
Parallelization of implicit Euler-type integration methods for stiff ordinary differential equations (ODEs) is obtained by decoupling the system into \(p\) subsystems for \(p\) processors. ``Internal'' solution components in each subsystem are treated implicitly, ``external'' solution components are extrapolated. The paper deals with the theory of this

Natural modes o f complex stiffness systems

For a vibrating dissipative system with hysteresis loop, complex (dynamic) stiffness is widely used. Although there are eigenvalue solvers available to solve the symmetric complex eigenvalue problems being produced, the physical interpretation of the eigensolutions which are no longer in complex conjugate pairs is generally impossible.
