However, their broad application in industry and research is limited due to the complexity of incorporated muscle controllers, the long simulation runtime, and the non-regular use of physiological motor control approaches. The purpose of this study is to address the challenges in all indicated directions by implementing a muscle controller with several physiologically inspired control strategies into an open-source extended Hill-type muscle model formulated as LS-DYNA user-defined umat41 subroutine written in the Fortran programming language. This results in increased usability, runtime performance and physiological accuracy compared to the standard muscle material existing in LS-DYNA. The proposed controller code is verified with extensive experimental data that include findings for arm muscles, the cervical spine region, and the whole body. Selected verification experiments cover three different muscle activation situations: (1) passive state, (2) open-loop and closed-loop muscle activation, and (3) reflexive behaviour. Two whole body finite element models, the 50th percentile female VIVA OpenHBM and the 50th percentile male THUMS v5, are used for simulations, complemented by the simplified arm model extracted from the 50th percentile male THUMS v3. The obtained results are evaluated additionally with the CORrelation and Analysis methodology and the mean squared error method, showing good to excellent biofidelity and sufficient agreement with the experimental data. It was shown additionally how the integrated controller allows simplified mimicking of the movements for similar musculoskeletal models using the parameters transfer method. Furthermore, the Hill-type muscle model presented in this paper shows better kinematic behaviour even in the passive case compared to the existing one in LS-DYNA due to its improved damping and elastic properties. These findings provide a solid evidence base motivating the application of the enhanced muscle material with the internal controller in future studies with Active Human Body Models under different loading conditions.", "issn" : "1617-7940", "refid" : "Martynenko2023", "doi" : "10.1007/s10237-023-01748-9", "bibtexKey": "MartynenkoEtAl23" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/26a31814c8d179f876532d07e3eed059f/testusersimtech", "tags" : [ "EXC2075","EXC310","PN2","PN4","selected" ], "intraHash" : "6a31814c8d179f876532d07e3eed059f", "interHash" : "03edbe7c427ba468f11012d3d68cc5e1", "label" : "Role of Rotated Head Postures on Volunteer Kinematics and Muscle Activity in Braking Scenarios Performed on a Driving Simulator", "user" : "testusersimtech", "description" : "", "date" : "2024-03-26 11:56:11", "changeDate" : "2024-03-26 11:56:11", "count" : 6, "pub-type": "article", "journal": "Annals of Biomedical Engineering","publisher":"Springer", "year": "2022", "url": "", "author": [ "Fabian Kempter","Lorena Lantella","Norman Stutzig","Jörg Fehr","Tobias Siebert" ], "authors": [ {"first" : "Fabian", "last" : "Kempter"}, {"first" : "Lorena", "last" : "Lantella"}, {"first" : "Norman", "last" : "Stutzig"}, {"first" : "Jörg", "last" : "Fehr"}, {"first" : "Tobias", "last" : "Siebert"} ], "volume": "51","number": "4","pages": "771-782", "research-areas" : "Engineering", "language" : "eng", "issn" : "0090-6964 and 1573-9686", "affiliation" : "Fehr, J (Corresponding Author), Univ Stuttgart, Inst Engn & Computat Mech, Pfaffenwaldring 9, D-70569 Stuttgart, Germany.
