[Unreleased]

To add

Long term

• plastic wave (probably impossible here as it requires too large changes); #### Middle term

• friction and damped boundary conditions (see DeJuhasz reference);

• elastic, mass, dashpot end conditions (see Graff reference);

• impacting mass (left end); #### Short term

• test and check indV argument of Waveprop class;

• plot Stress and Strain in Segment for WP2.

• Lagrangian x-t diagram keyword should appear and be in description

• modeling of impact on transfer flange (for tension testing simulation)

To change

[2.0.1] - 2022-04-19

Added

• more comments on the interpretation of space-time diagrams of the examples.

Changed

• Barhete is now BarSet, which is more meaningfull;

• Barhomo is now BarSingle, which is more meaningfull too.

[2.0.0] - 2022-03-08

Changed

• New name for the module (elwaspatid), identical to project name, for consitancy.

[1.1.0] - 2022-03-15

Added

• Segment.Z must be array and not scalar any more;

• Segment.resetImpedance to allow impedance variation inside Segment;

• WP2.plotDeSaintVenant displacement diagram plotting method;

• Waveprop.plotDeSaintVenant displacement diagram plotting method;

• fixed boundary condition for Waveprop;

• fixed boundary condition for WP2;

• compute Stress and Strain in Segment for WP2;

Changed

• plain boundary condition is now called infinite (meaningful).

[1.0.2] - 2022-03

Added

• detect end of contact between rod with displacement;

• update boundary conditions (segment.left, .right) accordingly;

• plot impedance of Segment, and of Barhete.

[1.0.1] - 2022-02

Added

• Waveprop: compute and plot displacement of nodes, stress in elements;

• WP2: compute displacement of nodes (experimental);

• WP2.getSignal: choice of time scale (s, ms, µs).

[1.0.0] - 2021

Added

• ElasticImpact class.

Changed

• use of plt.pcolormesh modified in WP2.subplot method;

• test cases are now external files (removed from bottom of module).

[0.8.0] - 2016

Added

• WP2 class to overcome the limitations of Waveprop.

[0.5.0] - 2014

Added

• Waveprop class.
