Adhesive contact of the Hertzian indenter with an incompressible elastic substrate bi-directionally stretched along the indenter principal planes of curvature is considered in the Johnson–Kendall–Roberts theoretical framework. An approximate model is constructed by examining energy release rate conditions only on the edges of the minor and major axes of the contact ellipse. The effect of weak coupling between fracture modes I and II is introduced using a phenomenological mode-mixity function.

I am creating this post to get some inputs on deriving the analytical solution to the 3D nonlinear elastic wave equation.

We present a novel image-based multiscale multigrid solver that can efficiently address the computational complexity associated with highly heterogeneous systems. This solver is developed based on an image-based, multiresolution model that enables reliable data flow between corresponding computational grids and provides large data compression. A set of inter-grid operators is constructed based on the microstructural data which remedies the issue of missing coarse grid information.

Recently, I guest-edited a special issue of the journal Entropy on Unified Mechanics Theory and related topics. All published papers are available for free download from the link below.

I hope that some of you will find this work interesting. We show that early cracking occurs in slow strain rate tensile testing (SSRT), which compromises the capabilities of this popular experiment for measuring hydrogen embrittlement susceptibility.
