Fig. 11.11 Quantitative evaluation of the performance of the Meshless Total Lagrange Explicit
Dynamics (MTLED) framework with the specialised visibility criterion for modelling surgical
cutting/dissection and soft tissue rupture. The results obtained when applying the MTLED
framework to model rupture-causing elongation of pia-arachnoid-complex tissue specimen are
compared with the experimental data obtained by Jin et al. [56] at the Bioengineering Centre,
Wayne State University. The strain rate is 0.05 s −1 . (a) The specimen deformation for the
overall sample elongation of 42.5% of the initial length predicted using the MTLED framework.
Dimensions are in mm; (b) photograph of the deformed tissue specimen. (Adapted from Jin [57]
(Bioengineering Centre, Wayne State University)). (c) Comparison of the nominal stress-strain
relationship predicted using the MTLED framework [58] with the experimental results reported in
[56]. (The figures and the photograph are adapted from [57, 58])
