A new data reduction scheme to obtain the mode II fracture properties of Pinus Pinaster wood [PDF]

open access: yes, 2006
In this work a numerical study of the End Notched Flexure (ENF) specimen was performed in order to obtain the mode II critical strain energy released rate (GIIc) of a Pinus pinaster wood in the RL crack propagation system.

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

Cosmic shear results from the deep lens survey - I: Joint constraints on omega_m and sigma_8 with a two-dimensional analysis

open access: yes, 2013
We present a cosmic shear study from the Deep Lens Survey (DLS), a deep BVRz multi-band imaging survey of five 4 sq. degree fields with two National Optical Astronomy Observatory (NOAO) 4-meter telescopes at Kitt Peak and Cerro Tololo.

Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

A novel hyperbolic shear deformation beam theory for functionally graded nonlocal nanobeams

open access: yesDiscover Applied Sciences
This paper introduces an innovative nonlocal hyperbolic shear deformation theory for the bending, buckling, and vibration analysis of functionally graded (FG) nanobeams. The theory is developed based on a displacement field that accounts for both bending

A refined quasi-3D higher-order shear deformation theory for static, free vibration, and buckling of laminated composite plates on kerr-type foundation

open access: yesNext Materials
Composite laminate plates are widely used in different engineering fields, yet existing higher-order shear theories (HSDTs) often fail to capture shear deformation and the coupled effects of elastic supports, leading to design inaccuracies.
