About

Python library that uses the rheological-dynamical analogy (RDA) to compute damage and effective buckling stress in prismatic shell structures.

This work is a part of the investigation within the research project [ON174027], supported by the Ministry for Science and Technology, Republic of Serbia. This support is gratefully acknowledged.

Installation

To install fsm_effective_stress run:

$ pip install fsm_effective_stress

Usage examples

Quick start:

>>> from fsm_effective_stress import compute_damage, compute_effective_stress

>>> omega =  103.9167 # [rad/s] natural frequency for undamaged state of structure
>>> omega_d = 60.0179 # [rad/s] natural frequency for damaged state of structure
>>> sigma_d = 19.4754 # [MPa] buckling stress for damaged state of structure

# [no unit] damage variable
>>> print "%.4f" % compute_damage(omega, omega_d)
0.6664

# [MPa] effective buckling stress
>>> print "%.4f" % compute_effective_stress(omega, omega_d, sigma_d)
58.3842

Please see the fsm_damage_analysis source code for more examples.
