How to use lumped damage mechanics: Two-dimensional solids.2026. V.C. Guimaraes, P.; Chang-Qi Pan.; A. Picón, R.; L.N.F. Amorim, D.; Yan-Gao Hu.; P.B. Proença, S.; Flórez López, J
This paper proposes an extension of Jean Lemaitre’s Continuum Damage Mechanics (CDM) into a unified framework denoted Lumped Damage Mechanics (LDM), capable of integrating diffuse micro-damage and localized fracture processes. […]
Low-order parametric modeling and control of air–fuel loops in industrial rotary dryers: A passive system identification approach.2026. “Rodríguez-Durán. V.G; Montero-Góngora.D; Columbié-Navarro.Á.O; Retirado-Mediaceja. Y; Zalazar.C; Narayan.S; Osorio.L.
Industrial rotary dryers with combustion chambers are among the most energy-intensive unit operations in nickel laterite processing, often operating below 50% thermal efficiency. This study develops low-order linear models for […]
Numerical Analysis of Unreinforced Masonry Arches and Vaults via Two-Dimensional Lumped Damage Mechanics.2026.Barros, K. R. A. G.; Cruz, A. K. S.; Cunha, R. N.; Amorim, D. L. N. F.; Picón, R.; Flórez López, J.
The structural analysis of historic buildings, including masonry arches and vaults, is essential for both preserving cultural heritage and ensuring their stability and continued functional use. The accurate description of […]
Systematic Generation of a Dataset to Study University Dropout in Chile Using Public Data and Open Source Frameworks. 2026. Ferreira, A.; Campos, D.; Lagos, D.; Leal, P.; Reinecke, C.
