This book is recommended for students and professors who intend to obtain knowledge about hyperelastic materials, nonlinear continuum mechanics and positional finite element method. Such special class of structures has great potential for engineering and industrial applications and for academic purposes. This is due to the fact that structural components may be highly deformable, as they are getting more and more versatile. The main purposes of this book are: to address some of the principal hyperelastic constitutive models; and to present the numerical implementation of such models in a...
