Isolated Points
Isolated points are the another type of entity (after nodes, elements or nodes of elements), at which the fatigue damage calculation can be prepared. They are intended to serve as a replace instead of strain gauges with locally acquired load histories, where the information concerning the loading of the rest of the structure is missing. Another potential use can be in the cases where the smooth specimens are loaded; here no FE-model is required.
Definition of isolated points is concentrated in the ISPOINT data_vector, which is unique inside the data_base. The isolated point is defined by its ID-name (12 characters at most), its coordinates and by normal line vector to it (only surfacial points are expected for any fatigue analysis). The set of all isolated points defined has a unique ID-name IP_ALL.
The isolated points have their own result files related by a reference to a set of isolated points.
Isolated points have an interesting feature in the fact, that they can be directly created inside PragTic interface.
