Similarily, soft material characterization was performed employing uniaxial
plate-compression testing, cf.
Sect. 4.2.1.2
. Via material parameter optimization,
the parameters of the reference material ''RD59'' and five additional parameter
sets derived from factorization (referred to as F5, F2, F0.75, F0.5 and F0.25) of the
experimental reference values were establisehd, Fig.
7.4
. The force-displacement
data of the material F0.5 for example, was generated by multiplying the ''RD59''-
