“…Initially developed in the field of civil engineering, the repeatability, adaptability, non‐destructive nature and time‐saving benefits of FEA triggered a rapid expansion into medical research (Belytschko et al, 1974; Brekelmans et al, 1972; Coburn, 1980; Huiskes & Hollister, 1993; Matthews & West, 1972; Rybicki et al, 1972; Smith & Cohen, 1984). Later, biologists and palaeontologists harnessed the potential of FEA to study the biomechanics of living (and extinct) organisms; since the early 2000s, FEA has grown in its application, becoming the go‐to method to analyse biomechanics in human anatomy (Gröning et al, 2012; Joshi et al, 2021), vertebrate feeding (e.g. in sharks Wroe et al, 2008, piranhas Grubich et al, 2012, dinosaurs Rayfield et al, 2001, mammals Tseng, 2009) and locomotion (e.g.…”

1. Finite element analysis (FEA) is a computational method used to predict the behaviour (stresses, strains and deformation) of a structure under predefined loading conditions. It can be applied to different biological structures, such as bone, to study defined muscle-driven scenarios. However, as muscle is an extremely complex structure to model, evolutionary biologists usually model muscle forces indirectly. In 2007, the BONELOAD MATLAB routine was developed to distribute muscle forces on a surface defined by the user. This routine then had to be coupled with a pre-existing FEA software (e.g. Strand7) to perform the analyses and has been widely used ever since.2. In this manuscript, we present a new method to run muscle-driven finite element simulations on a bone by distributing muscle forces on their insertions area, all within a single environment. We apply this protocol in three different situations: two biting simulations (unilateral and bilateral) and a shoulder flexion simulation.3. We demonstrate how to prepare the mesh, delineate the muscle origins and insertions, define the constraints, adjust material properties, choose a loading scenario (uniform, tangential or tangential-plus-normal), and extract the results. 4. Our automated script meshes the 3D model, defines the constraints and distributes muscle forces within a single simulation software: 'Metafor' (nonlinear solver, owned and distributed by Gesval S.A) or 'Fossils' (a new open-source linear static solver developed in the frame of this work). 'Metafor' and 'Fossils' can perform the entire protocol (from the meshing to the muscle-induced simulations) on high-resolution volumetric meshes (millions of tetrahedra) and rapidly, exceeding the processing time of other widely used software protocols by up to four times.We demonstrate that the results obtained from our protocol are highly congruent with brands such as Strand7. Thus, our protocol opens up the possibility to routinely and rapidly simulate the behaviour of high-precision muscle-driven FE models containing millions of tetrahedra.

Limb asymmetry can, and often does, cause various health problems. Blount bone staples (clips) are used to correct such uneven growth. This article analyzes the performance of a biomechanical staple during bone (tibia) growth arrest. The staples considered in this study were made of 1.4441 stainless steel, the model of tibia consisted of two materials representing corticalis and spongiosis. Hooke’s law was used for modeling materials’ behaviors for finite element analysis (FEA). The maxima of stress and total staple displacement were evaluated using the finite element method and verification of the results, along with the determination of the maximum loading (growing) force that the staples are capable of withstanding, was performed experimentally. The presented method can be used to determine the safety and usability of staples for bone growth arrest. According to our results, the design of Blount staples considered in this paper is safe and suitable for orthopedic treatment.
