Rheological–dynamical analogy: modeling of fatigue behavior

Rheological–dynamical analogy: visco-elasto-plastic behavior of metallic bars

“…Physical mechanism of the rheologicaldynamical analogy and the governing equations between parameters where confirmed by Mila sinovi c (2003). Based on the analogy, one very complicate nonlinear visco-elasto-plastic problem may be solved as a simpler linear dynamical one.…”

“…The cyclic strain amplitude e A have already been explained by Mila sinovi c (2003), where RDA was used to predict the fatigue limit…”

“…The fundamental statement of this theoretical tool and the governing differential equations have already been explained by Mila sinovi c (2000) where RDA was used to predict the buckling behavior of slender columns. In the second paper, the author (Mila sinovi c, 2003) demonstrates that RDA is also capable to model the fatigue behavior of axially, cyclically loaded bars.…”

Rheological-Dynamical Continuum Damage Model Applied to Research of the Rotational Capacity of a Reinforced Concrete Beams

“…For global failure analysis, the failure mechanism must be treated in a smeared manner, as a continuum with damage. Since about 1998 (Milašinović, [6,7]), a mathematical-physical analogy named rheological-dynamic analogy (RDA) has been pro- posed in explicit form to predict a range of inelastic and timedependent problems related to 1D prismatic rods, such as buckling, fatigue etc. This theory defines the critical mechanical properties of viscoelastoplastic (VEP) materials.…”

Relationship among S-N curves corresponding to different mean stresses or stress ratios

“…Cusumano and Chatterjee (2000) deduced a dynamics formula for fatigue damage evolution. Milašinović (2003) proposed a model of fatigue behavior named the rheological-dynamical analogy for inelastic materials and structures. Chamos et al (2010) found high stress sensitivity at high applied stresses due to very early crack initiation.…”
