Flat slab strengthening techniques against punching-shear

Engineering Structures, 2019
Abstract Over the years, the flat slab system has become a popular form of construction in many countries, particularly for multi-storey buildings such as offices or carparks. Nowadays, a considerable number of flat slab buildings requires strengthening against punching. Reasons are several, like design or construction errors, poor quality materials,

Comparison of gurson and lemaitre model in the context of blanking simulation of a high strength steel [PDF]

, 2017
The process of blanking takes place in a short band with high accumulated strain undergoing various stress triaxialities. Enhanced implementations for shear and compressive loads of Gurson’s and Lemaitre’s model are directly compared for the same ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

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

Advanced 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

Injectable Dual‐Crosslinked Poly(oligo(Ethylene Glycol) Methacrylate) Hydrogels Inspired by Mussel Adhesion for Cutaneous Wound Healing and Functional Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Injectable POEGMA‐DA hydrogels, dual‐crosslinked via dopamine self‐polymerization and dynamic hydrazone bonds, provide a safer alternative to invasive wound closure methods and toxic bioadhesives. Mimicking skin‐like mechanics, they achieve effective tissue adhesion for acute dermal wounds, supporting improved healing outcomes, including reducing ...

Blanking by means of the finite element method [PDF]

, 1998
This paper summarizes the results of simulating the blanking process by means\ud of the Finite Element Method. Unlike most of the research in this eld, the focus is not on the blanking process itself but on the deformed shape of a product after blanking.
