A secondary damage variable is defined to address the drawback of existing models for damage and healing in capturing the complete material failure. An energy-based damage evolution function is adopted for primary and secondary damage variables, and phenomenological healing evolution is defined. The proposed implicit elastic damage-healing model is implemented by the return-mapping technique, and the model response is demonstrated for different loading histories.en-USContinuum damage mechanicsElastic damage-healing modelMaterial failureMechanicsArticlehttps://doi.org/10.14429/dsj.74.198860976464Xpp. 321-328Article1123456789/592
