Good day, all!
Currently, I'm interested in the conformability of a membrane with a given surface.
An interesting paper by VL Popov which suggests many problems of tribology are still very far from being remotely solved. Despite the very detailed theories for example on rough contact using fractal surfaces on which we have debated mainly academically , there is not a single theory for any quantitative prediction of friction coefficient which can vary by 1 order of magnitude and its dependence on many variables, let alone wear coefficient which can vary up to 7 orders of magnitude. What is left to do, other than measure? Is tribology bound to be in practice just an
Here are some definitions which I have in my mind about the hierarchy of field theories of any kind. Please read them and correct me if there is any misunderstanding. Then I shall raise two questions based on this model of thought about the Mindlin's strain gradient and Eringen's nonlocal linear elasticity theories.
Definition 1. Two field theories are the same if and only if the field equations of one can be obtained from the other.

G'day all
Having a metal element with a notch like crack (assume sharp one, exhibits plasticity), what are the actual fracture mechanism (the phases the crack goes through) in the total fatigue-life.
please comment on these scenarios:
1- crack initiation life calculated from the (S-N, e-N), then using LEFM/EPFM to determine the cycles for the crack propagation to failure...
Q/ how to find the crack length between the two phases, I mean from which stresses and at which crack length we start the crack propagation life estimation.
My opinion is "Not yet".
What stops us from predicting the date on which the Larsen-C ice shelf will fail? http://www.parresianz.com/fracture/Larsen-B-and-peridynamics/

We would be hard-pressed to find an area of research that permeates so deeply in nearly all branches of physical sciences and mathematics as does the topic of homogenization [1].
