摘要：

An experimental determination of the superelastic exponent near the percolation threshold is presented. This exponent s' characterizes the pseudodivergence of the elastic constants of a mixture of very soft material (gel) and a rigid material (alumina and zirconia). From the measurement of the Young's modulus, s' is found to be 0.67 +/- 0.05. This value is in agreement with previous numerical simulations in 3D, and this indicates that very likely s' is smaller than the superconductor exponent.
