Comparison of experimental and theoretical values for SBR composites. a SBR/CB and b SBR/silica: materials exhibiting the Mullins effect (parallel stretching). c SBR/CB and d SBR/silica: materials not exhibiting the Mullins effect (perpendicular stretching). The experimental data were reproduced from Ref. 35
