Programmable logic sequential pneumatic system is developed for mechanical applications, like sealing, name punching, plate designing, etc. punching machine considered as inevitable in almost all the industries mechanical, electronic, food and automobile, To print hallmarks, logos a brand. In respect to reducing processing time by upgrading conventional automation integrating with control (PLC)...

The applications of GeoPolymer Concrete (GPC) with basalt-fiber-reinforced-polymer (BFRP) reinforcements could be alternative for conventional structural designs Portland Cement reinforced steel bars green and sustainable constructions. Very limited studies, however, have been carried out to investigate the performance GPC beams BFRP subjected static loads, no study their under impact load is a...

The level of maximum punching strength is major importance to design highly stressed slab-column connections and choose the type shear reinforcement. Since a couple years, there consensus that shear-reinforced concrete slabs can be defined as multiple reference without upper bound this load-increasing effect depends mainly on anchorage arrangement reinforcement elements. Despite numerous resear...

A number of theoretical problems are discovered in the application of degenerated models in punching process of ballistic shields. Insufficient knowledge of dynamic behavi ours of these models based on non-linear complex constitutive materials or combination of mixed rheological Maxwell models with linear elastic elements or dissipative is the main reason of the problems. In the engineering app...

This article describes a numerical study for the evaluation of punching shear behavior non-adherent prestressed flat slabs without reinforcement. Nonlinear three-dimensional models were used, along with finite element method (FEA) through ATENA software in order to validate constitutive adopted concrete and steel. The results compared experimental results. revealed good agreement among load cap...

abstract: The increase in the use of flat slabs and need openings for passage installations, such as hydraulic electrical, which significantly reduces punching shear resistance capacity slab, makes understanding influence this type structure extremely necessary. structural behaviour with at different distances from column was investigated through five square (1,800 mm x 1,800 130 mm) supported ...

Abstract This paper aims to study the behaviour of a circular footing resting on two granular layers, i.e., dense sand layer loose strata, subjected vertical and an inclined loading (?=0°, 10°, 20°, 30°) using finite element (FE) software PLAXIS-3D. The Mohr-Coulomb criterion is employed for analysis model, in which parameters are considered vary significantly; (1) thickness top (dense layer) (...

A finite element model (FEM) was constructed using specialized three-dimensional (3D) software to investigate the punching shear behavior of interior slab-column connections subjected to a moment-to-shear ratio of 0.15 m. The FEM was then verified against the experimental results of full-scale interior slab-column connections reinforced with glass fiber reinforcement polymer (GFRP) bars previou...

While self-controlled practice has been shown to enhance motor learning with various populations and novel tasks, it remains unclear if such effects would be found with athletes completing familiar tasks. Study 1 used a single case-study design with a world-champion kickboxer. We investigated whether giving the athlete a choice over the order of punches would affect punching velocity and impact...

Hot punching with two different strategies has been demonstrated as a new method of fabricating high aspect ratio 3D microstructures for drug delivery. It has been shown that this process is highly versatile with good replication fidelity and yield.
