Analysis of the delayed damage model for three one-dimensional loading scenarii
Abstract
The delayed damage model has been introduced by Allix and Deü [1] as a way to overcome spuriousmesh dependency in failure analysis involving damage and dynamic loading. The damage rate is boundedthrough a time scale which, combined with the wave speed, introduces implicitly a length scale. In this paper,the delayed damage model is analyzed through numerical experiments on three different loading cases of abar: a slow loading leading to a dynamic failure, pulses and impact. We observe and discuss the load levelneededforfailure(andthedependenceofthisloadlevelwithrespecttotheloadingrate),aswellasthedissipation and extent of the fully damaged zone at failure. Observations lead to the following conclusions.First, the delayed damage model has no regularization effect for a dynamic failure initiating from rest. Second,for pulse loadings, the loading rate has no influence on the minimal load level needed for failure (even thoughthe delayed damage model is a time-dependent model), and beyond this minimal load level for failure, theextentofthefullydamagezonerises,proportionallytothelengthscale.Third,regardingtheimpact,thevelocity needed to reach failure depends only the time-independent parameters of the models, and not theones linked to the delayed damage.
