Hi all,
I am looking for a general definition of the derivative of a tenorial product (e.g. when the expression for Stress contains nonlinear terms in deformation gradient, F ).
I start with a very simple example:
∂F_pq/∂F_mn = δ_pm δ_qn , i.e. Kronecker delta with first index of F_pq and first index of F_mn, and second Kronecker delta for second pair of indices q & n.
However the problem arises when we have a product of two or more tensors. Is the following (using chain rule) a valid derivative?
This video (LINK) attempts to give the big picture of solid mechanics along with the brief explanation of the constituent topics.

This is an educational outreach initiative targeted at all engineers interested in mechanics and seek simpler explanations. Kindly share if you learn something out of this !
Thanks,

Due to their large deformation capability, electroactive polymers are promising materials for several engineering applications. They can be used, for example, as actuators and sensors in artificial muscles, biomedical devices, microrobots, pumps, valves, etc. The research in this emerging field focuses in the multiphysics modeling of electroactive polymers and combines many aspects of structural mechanics, composite materials (for modeling composite electroactive polymers), and failure mechanisms of structural components and materials.

Element sulfur in nature is an insulating solid. While it has been tested that one-dimensional sulfur chain is metallic and conducting, the investigation on two-dimensional sulfur remains elusive. We report that molybdenum disulfide layers are able to serve as the nanotemplate to facilitate the formation of two-dimensional sulfur.
The Massachusetts Institute of Technology (MIT) Department of Mechanical Engineering seeks candidates for faculty positions starting July 2018 or on a mutually agreed date thereafter. Appointments will be at the assistant or untenured associate professor level. In special cases, a senior faculty appointment will be considered. Our department is committed to fostering interdisciplinary research that can address grand challenges facing our society.
We are looking for Postdoctoral Fellows with computational mechanics background specializing in one or more of these areas: solid mechanics, wave-structure interaction, fatigue and corrosion induced structural damage.
