However, studies still point to challenges regarding the complexity of the parameters involved, especially when the material exhibits partially developed strength and stiffness. A critical issue lies in understanding and predicting the specific types of structural failures that can occur during the printing process. This study proposes an analytical model to verify the structural element failure type during printing: plastic collapse or elastic buckling. The model is based on material physical nonlinearity, since it considers its properties evolving over time, according to the printing speed. The results indicated that the analytical model correctly reveals the failure type, with a difference of 3.7% in relation to the reference model. The parametric analyses showed that the proposed model is an accessible and effective tool to simulate the moment and type of the element failure, considering the parameters: stiffness, geometry and printing speed. additive manufacturing non-linear properties plastic collapse elastic buckling analytical model cement composites Full Text Cite Share Download PDF Status: Published Journal Publication published 04 Nov, 2025 Read the published version in The International Journal of Advanced Manufacturing Technology → Version 1 posted Editorial decision: Major Revisions Needed 30 Aug, 2025 Reviewers agreed at journal 21 Jul, 2025 Reviewers invited by journal 14 Jul, 2025 Editor assigned by journal 13 Jul, 2025 First submitted to journal 10 Jul, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
