Journal of Computation and Artificial Intelligence in Mechanics and Biomechanics (JCAIMB) is a scholarly online peer review free open access journal fully sponsored by "Publicações ISEP". All manuscripts are available in the ZENODO repository database, from OpenAIRE project, allowing an automatically abstracting and indexation and free open access. Thus, JCAIMB is committed to ensure free Open Science to both authors and readers and to publish only quality works, which are reviewed by experts in related field. Moreover, JCAIMB aims to publish quality original research works, following the scientific method of scholarly value in computational mechanics and biomechanics combined with several degrees of artificial intelligence, whose formulations and applications are properly demonstrated and validated. Nevertheless, innovative applications using commercial software packages are encouraged, as well as original and up-to-date revision manuscripts. In this issue, four manuscripts are published in JCAIMB: Finite element simulations of the electro-chemomechanical behavior of articular cartilage. Part I: theoretical formulation, by Mariana Bento, Fernando M.F. Simões and Benjamin Loret; Finite element simulations of the electro-chemomechanical behavior of articular cartilage. Part II: results and discussion, by Mariana Bento, Fernando M.F. Simões and Benjamin Loret; Structural analysis of the new Bioactive Kinetic Screw in titanium alloy vs. commercially pure titanium, by Carlos Aurelio Andreucci, Elza M. M. Fonseca and Renato N. Jorge; Structural analysis of healthy and degenerated intervertebral discs using meshless methods, by Rita Almeida and Jorge Belinha. Enjoy. The editorial team.
