The strain rate (ε˙) and temperature (T) dependent mechanical response of single crystal magnesium (Mg) micropillars compressed along the [2¯110] direction (a-axis) is investigated from room to 573 K 10-3 100 s-1. loading was chosen disfavour basal slip activation by a low Schmid factor, allowing investigation rate-sensitivities extension twinning prismatic slip. For T ≤ 423 K, plasticity governed for entire range applied rates. At > ε˙ 10 s-1, did not occur continuous plastic flow induced...
Bone is a natural composite possessing outstanding mechanical properties combined with lightweight design. The key feature contributing to this unusual combination of the bone hierarchical organization ranging from nano- macro-scale. anisotropic two orthogonal planes (along and perpendicular main axis) have already been widely studied. In work, we demonstrate dependence microscale compressive on angle between loading direction mineralized collagen fibril orientation in range 0° 82°. For...
In this work, 99.999% pure magnesium (Mg) single microcrystals have been deformed in [0001] compression (c-axis compression) and [101¯0] tension contraction) conditions at room temperature under loading rates ranging from 5 × 10−4 up to ∼590 s−1. The strain rate sensitivity apparent activation volume of prismatic pyramidal slip systems were evaluated. c-axis contraction, 45 s−1, the formation a new grain whose crystallographic characteristics do not correspond those well-known twin could be...
Osteogenesis imperfecta (OI) is an inheritable, genetic, and collagen-related disorder leading to increase in bone fragility, but the origin of its "brittle behavior" unclear. Because complex hierarchical structure, behaves differently at various length scales. This study aims compare mechanical properties human OI with healthy control extracellular matrix (ECM) level quantify influence degree mineralization. Degree mineralization were analyzed under dry conditions 12 fixed embedded...
The increased risk of fracture in the elderly associated with metabolic conditions like osteoporosis poses a significant strain on health care systems worldwide. Due to bone's hierarchical nature, it is necessary study its mechanical properties and failure mechanisms at several length scales. We conducted micropillar compression experiments ovine cortical bone assess anisotropic response lamellar scale over wide range rates (10−4 8·102 s−1). At microscale, exhibits rate sensitivity similar...
Preclinical studies often require animal models for in vivo experiments. Particularly dental research, pig species are extensively used due to their anatomical similarity humans. However, there is a considerable knowledge gap on the multiscale morphological and mechanical properties of miniature pigs' jawbones, which crucial implant direct comparison human tissue. In present work, we demonstrate multimodal framework assess jawbone quantity quality minipig model that could be further extended...

In this work, 99.999% pure magnesium (Mg) single microcrystals have been deformed in [0001] compression (c‑axis compression) and [-1010] tension contraction) conditions at room temperature under loading rates ranging from 5×10-4 up to ~590 s‑1. The strain rate sensitivity apparent activation volume of prismatic pyramidal slip systems were evaluated. c‑axis contraction, 45 s‑1, the formation a new grain whose crystallographic characteristics do not correspond those well‑known twin could be...
