Each layer has finite thickness overlying a rigid substratum. We assume that the layers are made up of isotropic, hyper-elastic and generalized neo-Hookean (similarly, compressible or incompressible) materials. Moreover, one layer contains heterogeneous materials and another contains homogeneous materials. The existence of nonlinear bright solitary SH waves in such layers can be found in the literature. Therefore, we aim to overcome the difficulty of a comparison of two nonlinear analyzes for this paper. Besides a comparison part, we add a discussion on some materials in homogeneous media. © 2020, Springer Nature Switzerland AG.eninfo:eu-repo/semantics/closedAccessBright solitary wavesHeterogeneous layerNonlinear SH wavesBook Chapter10.1007/978-3-030-38708-2_82-s2.0-85090044119143N/A121122
