An energy-minimal simulation is proposed to study the patterns and mechanical
properties of elastically crumpled wires in two dimensions. We varied the
bending rigidity and stretching modulus to measure the energy allocation,
size-mass exponent, and the stiffness exponent. The mass exponent is shown to
be universal at value DM​=1.33. We also found that the stiffness exponent
α=−0.25 is universal, but varies with the plasticity parameters s and
θp​. These numerical findings agree excellently with the experimental
results
