Mechanical interaction of human body with surrounding is mostly via soft tissues because human body is nearly entirely covered with them. Finite element method, extensively used in various fields of engineering, could not reach to a similar success in simulating soft tissues (especially for modeling the interaction with exoskeletal prosteses and orthoses) mainly because soft tissue mechanical behavior is not known in detail in addition to relatively complex mechanical response of soft tissues.

In vivo indenter experiments on soft biological tissues for identification of material models and corresponding parameters
Petekkaya, Ali Tolga; Tönük, Ergin; Department of Mechanical Engineering (2008)
Soft biological tissues, being live and due to their physiological structures, display considerably complex mechanical behaviors. For a better understanding and use in various applications, first study to be carried out is the tests made particularly as in vivo. An indenter test device developed for this purpose in the METU, Department of Mechanical Engineering, Biomechanics Laboratory is operational. In this study, in order to carry out precise and dependable tests, initially, various tests and improvement...
In-vivo testing of biological bulk soft tissues by a non-axisymmetric tip indenter using displacement and force control
Ashrafi, Parinaz; Tönük, Ergin; Bozkurt, Murat; Department of Biomedical Engineering (2015)
Soft tissues of human body have complex structures and different mechanical behaviors than those of traditional engineering materials. There is a great urge to understand tissue behavior of human body. Experimental data is needed for improvement of soft tissue modeling and advancement in implants and prosthesis, as well as diagnosis of diseases. Mechanical behavior and responses change when tissue loses its liveliness and viability. One of the techniques for soft tissue testing is indentation, which is appl...
Indentation and Observation of Anisotropic Soft Tissues Using an Indenter Device

In vivo indentation of lower extremity limb soft tissues
Silver-thorn, M.b.; Tönük, Ergin; Kemp, J. (1999-12-01)
In vivo rate-controlled indentation tests, force relaxation trials, and creep studies were conducted on the soft tissues of the residual limbs of individuals with trans-tibial amputation. The cyclic indentation tests indicated that the bulk soft tissue response to compressive load is nonlinear and rate-dependent. The force relaxation studies indicated that substantial relaxation (35-80%) may occur, with equilibration typically occurring in less than 60 seconds. Most of this relaxation (20-70%) occurred with...
A comparative study of anisotropic hyperelastic models of biological soft tissues
Açan, Alp Kağan; Dal, Hüsnü; Department of Mechanical Engineering (2021-8)
In the last two decades, there has been significant growth of interest in the mechanical behavior of biological soft tissues approached from the continuum mechanical perspective. A plenty of constitutive models have been proposed that represent the anisotropic hyperelastic behavior of biological soft tissues. Generally, invariant and fiber dispersion-based models are two main categories considered during the modeling steps. Among the anisotropic models, fiber dispersion-based constitutive models are known t...
