Computation concepts

This section of the help reports on various ways how to solve the puzzle of the fatigue life calculation. The brief description of the main chapters here follows:

* Examined planes - different schemes concerning the selection of planes used for a damage parameter evaluation.

* Notch effect - notches influence the local stress/strain fields by forming a highly stressed area and by induced plasticity.

* Non-linear FE solution - what to do if the Hooke's law is no longer valid, but we need to work with real elastic-plastic values?

* Load history decomposition - the semi-continuous record of load history has to be fragmented into separate cycles. How to do that?

* Other influencing factors - this group of other factors influencing the final computation is focused today only on the LESA method.

* Theory basis - some necessary universal concepts required for understanding.
