Poroelastic Modeling of Highly Hydrated Collagen Hydrogels: Experimental Results vs. Numerical Simulation with Custom and Commercial Finite Element Solvers

With the non-stop advances in computational methods and tools, researchers have a wide range of possibilities when it comes to choosing the most appropriate software for their work.

In the field of biomechanics and biomaterials, one of the most used tools to predict and understand the behaviour of materials and devices is the finite element method, which allows for the computational evaluation of loads and deformations of a given structure.

The present work deals with the comparison of two different finite element programs on the modelling of one of the most important biomaterials: collagen. On the one hand, V-Biomech® is a custom solver, developed by a group of researchers to mimic the behaviour of biomaterials such as this very same collagen. On the other hand, Abaqus® is a widely spread software, which covers the modelling of most materials and possible designs, even if not specifically collagen or other biomaterials.

The interesting outcome of this work is that both programs have shown to be able to mimic the behaviour of collagen, as previously experimentally registered by other researchers in the field. Thus, the researcher working on the behaviour of highly hydrated biomaterials has the option of choosing a large spectrum commercial tool or a dedicated one, depending on the needs of the work.
