Comparison experimental/numerical results

• Case A: Maximal initial displacement: 0.87 mm. Plucking at x = 0.64 m from the nut. The observed variable is the displacement at 9 mm from the bridge.

Experimental signal:



Numerical signal:



• Case B: Maximal initial displacement: 3.6 mm. Plucking at x = 0.64 m from the nut.
Except when specified, contact parameters are $\alpha \; =\; 1.5$ and $K\; =\; 1013$.
