A Determination of fracture toughness in plain concrete specimens by R curve

open access: yesFracture and Structural Integrity, 2019
Since the last two centuries, concrete has become the number one building material in the world. Therefore, we are interested in studying the mechanical behavior at failure of this material and calculate its toughness.

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Effect of L-thyroxine on bone biomechanical and morphometric parameters in rats

open access: yesBMC Veterinary Research
Background Morphometric measurements and biomech anical tests are very crucial in determining the effects of drugs and chemicals on bones. L-thyroxine is often used instead of thyroid hormone in research conducted on experimental animals.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Comparison of flexural strength of different composite restoratives using the three-point bending test

open access: yesThe Journal of Qazvin University of Medical Sciences, 2016
Background: Composite is one of the restorative materials used for the posterior teeth. The strength of restorative material is important due to heavy loading on the posterior teeth.

The parameter estimation from three-point bending tests [PDF]

open access: yes, 2022
We would like to use an inverse procedure to determine the two parameters of the model using the recorded experimental data. The recorded parameters must describe the experiment completely and unambiguously. In the case of three-point bend- ing tests, the complete set of recorded data includes force, displacement, and CMOD values. Our work compares the

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.
