Given enough time the body\u2019s musculature can generate force, affect the body\u2019s movements, and change the risk of some injuries. The finite-element code LS-DYNA is often used to simulate the movements and injuries sustained by the digital human body models as a result of an accident. In this work, we evaluate the accuracy of the three muscle models in LS-DYNA (MAT_156, EHTM, and the VEXAT) when simulating a range of experiments performed on isolated muscle: force-length-velocity experiments on maximally and sub-maximally stimulated muscle, active-lengthening experiments, and vibration experiments. The force-length-velocity experiments are included because these conditions are typical of the muscle activity that precedes an accident, while the active-lengthening and vibration experiments mimic conditions that can cause injury. The three models perform similarly during the maximally and sub-maximally activated force-length-velocity experiments, but noticeably differ in response to the active-lengthening and vibration experiments. The VEXAT model is able to generate the enhanced forces of biological muscle during active lengthening, while both the MAT_156 and EHTM produce too little force. In response to vibration, the stiffness and damping of the VEXAT model closely follows the experimental data while the MAT_156 and EHTM models differ substantially. The accuracy of the VEXAT model comes from two additional mechanical structures that are missing in the MAT_156 and EHTM models: viscoelastic cross-bridges, and an active titin filament.

While the previous discussion of I40 has been centered on technologies and standards, our focus is on business models (BM) for and enabled by I40. Having the right I40 BM will ultimately decide about companies\u2019 market positions and profitability. This calls for a systematic process for business model innovation (BMI). The previous academic literature has offered mostly conceptual reviews to date. Empirical analyses of management approaches and processes applied for BMI are scarce. Based on an exploratory research design, we present the results of a comparative interview study with large companies and industry associations. We analyze I40 business model characteristics, provide an in-depth perspective of companies\u2019 processes, structures and tools for BMI and derive upcoming practices as well as key competencies for BMI in the course of I40. Our results indicate a diverse picture. While some companies have dedicated BMI structures in place and lead I40 BMI, others could benefit from complementing existing product and service development with a systematic approach to BMI, building the fundamental capability to exploit the opportunities of I40.", "location" : "http://ssrn.com/paper=2571033", "language" : "English", "doi" : "10.2139/ssrn.2571033", "bibtexKey": "burmeister2015business" } ] }
