What numerical analysis procedures are available in Histra?

Histra implements:

  • modal analysis, for the dynamic characterization of the modes and vibrations’ frequencies of the structure;
  • force-controlled incremental nonlinear static analysis, monotonic or cyclic, based on the standard or modified Newton-Raphson method;
  • incremental nonlinear static analysis with displacement control, monotonic or cyclical, based on the Arc Length method or with the Control-Displacement method;
  • the incremental nonlinear static analysis can be performed by activating the LineSearch routine according to the Interpolated, RegulaFalsi, Bisection, Secant procedures.

All this makes the numerical procedure extremely fast and robust in step resolution, managing to capture any degradations in the global response due to constitutive links with softening and cyclical degradation.
