Punching shear performance of star-shaped steel plates reinforced RC slab-column connections
Case Studies in Construction Materials, 2023 The progressive collapse of flat plate structures due to brittle punching shear failure of reinforced concrete (RC) slab-column connections is a major concern in structural engineering.

Kinematic flow patterns in slow deformation of a dense granular material [PDF]
Granular Matter 17(5) 2015 553--565, 2015 The kinematic flow pattern in slow deformation of a model dense granular medium is studied at high resolution using \emph{in situ} imaging, coupled with particle tracking. The deformation configuration is indentation by a flat punch under macroscopic plane-strain conditions. Using a general analysis method, velocity gradients and deformation fields are

Anisotropic behaviour law for sheets used in stamping: A comparative study of steel and aluminium [PDF]
Comptes Rendus Mecanique 331, 1 (2003) 33-40, 2008 For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simulation results are not yet as reliable as those of steel. Punch-strength and spring-back phenomena are not correctly described. This study on aluminium validates the behaviour

Shear-induced contact area anisotropy explained by a fracture mechanics model [PDF]
Physical Review E , American Physical Society (APS), 2019, 99 (5),
pp.053005, 2019 This paper gives a theoretical analysis for the fundamental problem of anisotropy induced by shear forces onan adhesive contact, discussing the experimental data of the companion Letter. We present a fracture mechanicsmodel where two phenomenological mode-mixity functions are introduced to describe the weak couplingbetween modes I and II or I and III ...

Determination of the Punching Cross-Section of Reinforced Concrete Flat Slabs [PDF]
, 2016 In this paper, the punching shear resistance of slabs without punching shear reinforcement is investigated. We assumed that the punching shear resistance can be characterized by the shear resistance of the concrete compression zone, and that the load ...

Finite element implementation of punching shear behaviors in shear-reinforced flat slabs
Ain Shams Engineering Journal, 2015 Punching shear reinforcement systems such as studs and stirrups are used to improve the punching shear strength of flat slabs. A three dimensional finite element model (FEM) is developed through Ansys 10 computer software, to carry out the nonlinear ...
