A cluster-based incremental potential approach for reduced order homogenization of bones.

We develop a cluster-based model order reduction (called C-pRBMOR) approach for efficient homogenization of bones, compatible with a large variety of generalized standard material (GSM) models. To this end, the pRBMOR approach based on a mixed incremental potential formulation is extended to a clustered version for a significantly improved computational efficiency. The microscopic modeling of bones falls into a mixed incremental class of the GSM framework, originating from two potentials.

Effects of cooking methods on antioxidant activity and acrylamide formation in red bell pepper ().

Unlabelled: Red bell pepper is a popular and nutritious vegetable. In this study, oven cooking (OV), air-frying (AF), and infrared grilling (IR) were used to cook red bell peppers at different temperatures (170, 180, 190, and 200 °C). Changes in the total phenolic content, ascorbic acid content, antioxidant activity, and sugar and acrylamide content in red bell peppers were evaluated before and after cooking.

Microstructural Modeling and Strengthening Mechanism of TiB/Ti-6Al-4V Discontinuously-Reinforced Titanium Matrix Composite.

A novel modeling method was proposed to provide an improved representation of the actual microstructure of TiB/Ti-6Al-4V discontinuously-reinforced titanium matrix composite (DRTMC). Based on the Thiessen polygon structure, the representative volume element (RVE) containing the complex microstructures of the DRTMC was first generated. Thereafter, by using multiple user-defined subroutines in the commercial finite element software ABAQUS, the application of asymmetric mesh periodic boundary conditions on the RVE was realized, and the equivalent elastic modulus of the DRTMC was determined according to the homogenization method.
