Rupture assessment of rubber/clay nanocomposites containing a crack by means of an energy-based fracture criterion

Due to the growing use of nanotechnology in the modern era, the application of nanomaterials in elastomers has also been increased. Although some limited experiments are available in the previous studies regarding the fracture behavior of rubber nanocomposites containing a crack, no criteria have be...
