Materials modelling has established itself as an essential analysis not only to study the insight of complex physical phenomena appearing in the soft or condensed matter but also to realize the emerging trend of 'reverse engineering' as a keystone for technological innovations. The cover photo of this September 2019 issue describes the bio interaction between graphene and enzyme protein for bioelectronics applicable in battery, fuel cell and biosensing applications and dedicated to celebrating the 6th anniversary of Nobel Prize in Chemistry on “Multiscale models for complex chemical systems”.

In this study the stress fields under uniaxial tension of the plane with arc cut were calculated. To describe the concentration of normal and shear stresses in the areas of the crack ends, new characteristics based on equilibrium conditions were introduced. The influence of the angle of the crack arc opening and the direction of the plane tension was studied. It was found that those factors changed the value and the stresses sign at the crack ends. The opening angles of arc cracks and tension direction promoting the development of cracks under the influence of tensile strain, tensile stresses or combination of the stresses were determined. The promoting conditions that inhibit the cracks were studied. © VBRI Press.
