The trend in biomaterials development has now headed for tailoring the properties and making hybrid materials to achieve the optimal performance metrics in a product. Modern manufacturing processes along with advanced computational techniques enable systematical fabrication of new biomaterials by design strategy. Functionally graded materials as a recent group of hybrid materials have found numerous applications in biomedical area, particularly for making orthopedic prostheses. This article, therefore, seeks to address the following research questions: (RQ1) What is the desired structure of orthopedic hybrid materials? (RQ2) What is the contribution of the literature in the development of hybrid materials in the field of orthopedic research? (RQ3) Which type of manufacturing approaches is prevalently used to build these materials for knee and hip implants? (RQ4) Is there any inadequacy in the methods applied?

“…It was evident that our knowledge of complex biomechanical behavior has been driven by the development of new technologies and new biomaterials as well as the novel application of existing techniques. Ultimately, EM has played an important role in the growth of the field by publishing a wide breadth of noteworthy papers, especially in relation to the development of innovative techniques, technologies, and biomaterials [6][7][8][9][10]. Consequently, as the unique challenges of this field became more apparent to the EM community, new scientific innovations have evolved in response.…”

Biomechanics is a young field that entails the study of the mechanical aspects of the life and health sciences. The growth of this field can be attributed to the growth of cutting-edge technologies that enable scientists to investigate the mechanics of life with increasing acuity. Founded in 1961, the journal Experimental Mechanics (EM) has had an important role in the growth and scholarship of the field of biomechanics. From the mid-1960's to mid-1970's, relevant publications in EM focused on characterizing potential bioimplants and exploring the mechanical properties of connective tissues. The next two decades witnessed a clear drop in biomechanics papers in EM, perhaps due to the rise of biomechanics-specific societies and journals that offered a more dedicated audience while EM sought a more varied readership. More recently, there has been a resurgence of biomechanics publications in EM, including 3 recent special issues devoted to the subject. The journal has brought forth an impressive range of biomechanics related papers including cellular and nanoscale studies, characterization of biological tissues and novel biomaterials, and most importantly, the development of novel technologies and devices that are applicable across the entire field. Digital image correlation and digital volume correlation are examples of techniques presented in EM that have been applied to numerous biomechanics problems. Although the field has exhibited exponential growth in the past 15 years, a myriad of scientific questions, especially on the cellular and subcellular level, remain to be answered. EM should cultivate its future role in shaping this exciting field.

“…More recently, new micromechanical numerical methods have been developed that can model the behavior of more complex porous microstructures, such as randomly dispersed pores (Roberts 2002, Tseng 2004). Many of these modeling advances have been developed in order to describe the behavior of natural materials, such as cork, as well as synthetic materials with engineered microstructures at multiple length scales, such as biomimetic or bio-inspired materials (Bruck 2007). A particularly noteworthy advance, computer-based topology optimization, was applied to the minimization of weight in the design of structural components using homogenization methods (Bendsøe and Kikuchi 1988).…”

A new approach for optimizing the mechanical behavior of porous microstructures for porous materials by design

A high-fidelity generalized method of cells (HFGMC) model for the micromechanical behavior of porous and composite microstructures has been previously developed. Based on this model, a new approach has been developed to optimize porous microstructures for ‘porous materials by design’. This approach uses a combination of genetic algorithms (GA) (stochastic), coarse (periodic) and Newton–Raphson (gradient) optimization methods. In order to parametrize the unit cell of the microstructure for optimization and satisfy continuity conditions for the method of cells, lines of mass are used in each direction of the unit cell. Due to the nature of the optimization problem for porous microstructures, there can be multiple choices of mechanical and microstructural characteristics (e.g. axial stress, transverse strain, and mass) for the objective function (i.e. multi-objective) implying a Pareto optimality problem. For the porous materials by design problem based on mechanical characteristics, a predescribed mechanical response was chosen for a random distribution of mass to fit via a least squares objective function. The effects of implementing the combination of optimization methods on their convergence rate and optimized solutions were then studied, as well as variations in the weighting of the objective functions. A hyperelastic material behavior, Mooney–Rivlin, typically associated with natural and synthetic rubbers, is chosen to demonstrate the ability to optimize an engineered microstructure for a new class of super-lightweight energy-absorbing materials. These results indicate that the combination of the GA, coarse search and Newton–Raphson optimization techniques can substantially accelerate the convergence rate. Also, there is significant variability in the optimized microstructure depending on the choice of the weights for the associated Pareto optimality, as well as the choice of terms for the objective function. Parametrizing the porous microstructure using multiple lines of mass can create a more complex microstructure, but common centers of mass should be employed to minimize mass while improving convergence rates and optimal constitutive behavior. This new approach was applied to identify microstructures for three new porous materials by design: (a) a superelastic polymer, (b) an incompressible material and (c) an auxetic material.
