High strain rate mechanical behavior of seashell-mimetic composites: Analytical model formulation and validation

Biomimetic Materials by Freeze Casting

“…92 Therefore, it is no wonder several research groups focus on freeze casting and subsequent polymer infiltration to fabricate hybrid inorganic-organic composites. [19][20][21][22][29][30][31]37,38 …”

“…Furthermore, chemical grafting of the PMMA to the Al 2 O 3 surfaces promoted strong covalent bonding between the two phases, which helped protect against interfacial shear and subsequent delamination. 20,21,30,38 Bone Replacements Several attempts to fabricate freeze-cast scaffolds for bone replacement materials have been reported. 12,13,19,31, Porous HA scaffolds developed by Deville et al 41 have an interconnected porosity with lamellar pores 10-50 lm wide and high compressive strengths up to 145 MPa, nearly that of cortical bone (Fig.…”

“…20 There are a variety of potential applications for porous ceramics and hybrid composites fabricated by freeze casting. Biomimetic materials, such as structural composites [19][20][21][22][29][30][31]37,38 that may be useful as high-performance components in industries ranging from aerospace to automotive manufacturing and potential bone replacements 12,13,19,31, are most encouraging and are the primary focus of this article. Other potential applications for freeze-cast materials with complex shapes and designer microstructures include separation filters, insulators, sensors, electrodes, catalyst supports, fuel cells, and piezoelectric devices.…”

Temperature dependent work hardening in Ti–6Al–4V alloy over large temperature and strain rate ranges: Experiments and constitutive modeling

“…2. According to the one dimensional stress propagation theory, the average strain, stress, and strain rate can be calculated by the measured incident, reflected and transmitted pulses, e I , e R and e T , respectively, according to the following equations [22]:…”

“…The phenomenological models which are commonly calculated according to the flow stress responses, for example, the models proposed by Johnson and Cook [13], Seo et al [14], Sung et al [15], Steglich et al [16], and the KHL models [17,18], etc. While, the physical based models [19][20][21][22] were commonly developed involving the physical state of the materials (e.g. grain size, dislocation density, etc.…”
