The method is designed to work at haptic feedback rates (i.e., around 1kHz). Tissue tearing is simulated under the general framework of continuum damage mechanics. The problem is stated as a general, multidimensional parametric problem, which is solved by means of Proper Generalized Decomposition (PGD) methods. One of the main novelties is the reduction of history-dependent problems, such as damage mechanics, by resorting to an approach in which a reduced-order field of initial damage values is considered as a parameter of the formulation. We focus on the laparoscopic cholecystectomy procedure as a general example of the performance of the method. 000074891 536__ $$9info:eu-repo/grantAgreement/ES/CICYT/DPI2014-51844-C2-1-R$$9info:eu-repo/grantAgreement/ES/DGA/T88$$9info:eu-repo/grantAgreement/ES/MINECO/DPI2015-72365-EXP 000074891 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000074891 590__ $$a2.338$$b2017 000074891 591__ $$aMATHEMATICS, INTERDISCIPLINARY APPLICATIONS$$b24 / 103 = 0.233$$c2017$$dQ1$$eT1 000074891 591__ $$aMATHEMATICAL & COMPUTATIONAL BIOLOGY$$b11 / 59 = 0.186$$c2017$$dQ1$$eT1 000074891 591__ $$aENGINEERING, BIOMEDICAL$$b32 / 78 = 0.41$$c2017$$dQ2$$eT2 000074891 592__ $$a1.021$$b2017 000074891 593__ $$aComputational Theory and Mathematics$$c2017$$dQ1 000074891 593__ $$aModeling and Simulation$$c2017$$dQ1 000074891 593__ $$aBiomedical Engineering$$c2017$$dQ1 000074891 593__ $$aSoftware$$c2017$$dQ1 000074891 593__ $$aApplied Mathematics$$c2017$$dQ2 000074891 593__ $$aMolecular Biology$$c2017$$dQ3 000074891 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000074891 700__ $$0(orcid)0000-0002-9135-866X$$aAlfaro, Icíar$$uUniversidad de Zaragoza 000074891 700__ $$0(orcid)0000-0003-3003-5856$$aGonzález, David$$uUniversidad de Zaragoza 000074891 700__ $$aChinesta, Francisco 000074891 700__ $$0(orcid)0000-0003-1017-4381$$aCueto, Elías$$uUniversidad de Zaragoza 000074891 7102_ $$15004$$2605$$aUniversidad de Zaragoza$$bDpto.
