Simulation Results of a Finite Element Discbrake

This dataset contains simulation results from a finite element (FE) model of a heated disc brake, represented in two configurations:

Simple Discbrake A lower-resolution FE model featuring a single heated area.

1 layer, 60 elements, 146 nodes 7 degrees of freedom (DOFs) per node, 998 DOFs in total

Discbrake with Hole and Three Heated Areas A higher-resolution FE model featuring a central hole and heating applied at three locations on both sides.

2 layers, 1390 elements, 2250 nodes 7 DOFs per node, 15750 DOFs in total

Both models are implemented in the commercial simulation software Abaqus.

Simulation Setup

Heat is applied through designated heat input areas with a constant heat flux of 5×106 ± 4.99×106 W/m². Material properties are varied:

Heat conductivity Density

Each simulation covers the time interval [0, 3] seconds for the simple discbrake and [0,10] seconds for the discbrake with a whole. Initial conditions are set to zero. Parameter vectors are sampled quasi-randomly using Halton sequences.

Output Data

Each simulation exports displacements and temperatures at all nodes. Velocities are computed using a second-order central difference scheme to extend the mechanical state.
