Push–out Test of Timber Concrete Composite Construction [PDF]
Engineering and Technology Journal, 2022 In this study, push – out test specimen is proposed to explore the behavior of shear connectors in timber–concrete composite beams. Since there are no standard shapes and dimensions for determining the strength of connectors, push–out specimens such as ...

Debonding criterion for the piezoelectric fibre push-out test [PDF]
Philosophical Magazine Letters, 2006 A theoretical model of piezoelectric fibre push-out is developed within the framework of a modified shear-lag theory to study stress and electrical field transfer. Based on the model, a debonding criterion for the piezoelectric effect is presented utilizing a fracture-mechanics approach to investigate the debonding process of piezoelectric fibre in the

In-house 3D printed porous implants: does strontium-coating enhance osseointegration? An in-vivo study in large animals [PDF]
Frontiers in SurgeryIntroductionEarly osseointegration is essential for the long-term success of uncemented custom-made prostheses, particularly in oncologic bone reconstruction where bone stock is compromised. Strontium (Sr) has demonstrated osteogenic potential, and Ti-Sr-

Concrete modeling in finite element push-out test simulations [PDF]
, 2023 Push-out tests are commonly used to investigate the shear performance of mechanical connectors applicable in steel-concrete composite beams. These tests can be complemented by numerical finite element simulations to reduce the need for extensive experimental testing.

Push-out tests of shear dowels
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Continuous shear connectors in a shape of dowels are one of the newer shapes of composite steel-concrete bridges. In this article results of push-out tests of such a dowel with geometry designed at Faculty of Civil Engineering, Technical University of Kosice are presented and compared to the previous research.

Material characteristics of push-out tests
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Two types of push-out tests were carried out at the Centre of Research and Innovation in Construction, the Technical University of Košice - one at a composite based on steel continuous shear connector and the second one at the same connector, however made of glass-laminate material.
