“…While skeletal muscle tensile studies are common (Abraham et al, 2012; Calvo et al, 2010; Gras et al, 2012; Morrow et al, 2010; Takaza et al, 2012; Wheatley et al, 2016), separate investigations have determined the tissue to be stiffer in the longitudinal direction (Morrow et al, 2010) or the transverse direction (Takaza et al, 2012). Our data for fresh samples agree well with Takaza et al for both transverse isotropy (transverse stiffer than longitudinal) and in terms of general stress-strain shape (longitudinal is nonlinear, transverse appears linear).…”

The passive tensile properties of skeletal muscle play a key role in its physiological function. Previous research has identified conflicting reports of muscle transverse isotropy, with some data suggesting the longitudinal direction is stiffest, while others show the transverse direction is stiffest. Accurate constitutive models of skeletal muscle must be employed to provide correct recommendations for and observations of clinical methods. The goal of this work was to identify transversely isotropic tensile muscle properties as a function of post mortem handling. Six pairs of tibialis anterior muscles were harvested from Giant Flemish rabbits and split into two groups: fresh testing (within four hours post mortem), and non-fresh testing (subject to delayed testing and a freeze/thaw cycle). Longitudinal and transverse samples were removed from each muscle and tested to identify tensile modulus and relaxation behavior. Longitudinal non-fresh samples exhibited a higher initial modulus value and faster relaxation than longitudinal fresh, transverse fresh, and transverse rigor samples (p<0.05), while longitudinal fresh samples were less stiff at lower strain levels than longitudinal non-fresh, transverse fresh, and transverse non-fresh samples (p<0.05), but exhibited more nonlinear behavior. While fresh skeletal muscle exhibits a higher transverse modulus than longitudinal modulus, discrepancies in previously published data may be the result of a number of differences in experimental protocol. Constitutive modeling of fresh muscle should reflect these data by identifying the material as truly transversely isotropic and not as an isotropic matrix reinforced with fibers.

“…While computational models of skeletal muscle have been developing since the introduction of the Hill model in 1938 (Hill, 1938), there have been relatively few studies of muscle tensile material properties at the tissue level (Abraham et al, 2012; Takaza et al, 2012), with the majority of studies evaluating compressive properties (Böl et al, 2014; Pietsch et al, 2014; Van Loocke et al, 2009, 2008, 2006). Studies of the structural response of individual muscle fibers (Meyer et al, 2011) and intact muscles (Calvo et al, 2010; Gras et al, 2012; Myers et al, 1998) are more prevalent. Since skeletal muscle is a highly organized collection of fibers and a collagenous connective matrix, which plays a key role in force transmission (Meyer and Lieber, 2011), it may be difficult to extrapolate whole muscle behavior from results of studies of individual fibers.…”

Introduction Computational modeling of skeletal muscle requires characterization at the tissue level. While most skeletal muscle studies focus on hyperelasticity, the goal of this study was to examine and model the nonlinear behavior of both time-independent and time-dependent properties of skeletal muscle as a function of strain. Materials and Methods Nine tibialis anterior muscles from New Zealand White rabbits were subject to five consecutive stress relaxation cycles of roughly 3% strain. Individual relaxation steps were fit with a three-term linear Prony series. Prony series coefficients and relaxation ratio were assessed for strain dependence using a general linear statistical model. A fully nonlinear constitutive model was employed to capture the strain dependence of both the viscoelastic and instantaneous components. Results Instantaneous modulus (p<0.0005) and mid-range relaxation (p<0.0005) increased significantly with strain level, while relaxation at longer time periods decreased with strain (p<0.0005). Time constants and overall relaxation ratio did not change with strain level (p>0.1). Additionally, the fully nonlinear hyperviscoelastic constitutive model provided an excellent fit to experimental data, while other models which included linear components failed to capture muscle function as accurately. Conclusions Material properties of skeletal muscle are strain-dependent at the tissue level. This strain dependence can be included in computational models of skeletal muscle performance with a fully nonlinear hyperviscoelastic model.

“…The sacrifice has been done early morning. Immediately after the sacrifice, the tongue was cut from the larynx and immersed in a saline solution at 4°C to keep it fresh and prevent its degradation (Hernández et al 2011 andGras et al 2012). Due to the complex structure and the direction variation of tongue fibers (Gilbert et al 2006), cutting an appropriate sample with a fixed fiber direction from each muscle part is difficult in practice.…”

Material properties of the human tongue tissue have a significant role in understanding its function in speech, respiration, suckling, and swallowing. Tongue as a combination of various muscles is surrounded by the mucous membrane and is a complicated architecture to study. As a first step before the quantitative mechanical characterization of human tongue tissues, the passive biomechanical properties in the superior longitudinal muscle (SLM) and the mucous tissues of a bovine tongue have been measured. Since the rate of loading has a sizeable contribution to the resultant stress of soft tissues, the rate dependent behavior of tongue tissues has been investigated via uniaxial tension tests (UTTs). A method to determine the mechanical properties of transversely isotropic tissues using UTTs and inverse finite element (FE) method has been proposed. Assuming the strain energy as a general nonlinear relationship with respect to the stretch and the rate of stretch, two visco-hyperelastic constitutive laws (CLs) have been proposed for isotropic and transversely isotropic soft tissues to model their stress-stretch behavior. Both of them have been implemented in ABAQUS explicit through coding a user-defined material subroutine called VUMAT and the experimental stress-stretch points have been well tracked by the results of FE analyses. It has been demonstrated that the proposed laws make a good description of the viscous nature of tongue tissues. Reliability of the proposed models has been compared with similar nonlinear visco-hyperelastic CLs.
