The predictive performance of design models for the punching resistance of SFRC slabs in inner column loading conditions [PDF]

, 2012
In the recent years steel fibre reinforced concrete (SFRC), in a volume percentage between 0.75 and 1.25, is being proposed to build slabs supported on piles and slabs supported on columns, where the unique conventional reinforcement is composed of ...

Multi-fixed smeared 3d crack model to simulate the behavior of fiber reinforced concrete structures [PDF]

, 2008
When a concrete structure is subjected to a multi-stress state, different crack modes can be developed. To simulate with enough accuracy these fracture modes, a three dimensional model must be used.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Canola Fiber as Reinforcement for Composites: Effect of Fiber Extraction and Processing Method on Fiber Properties, Nonwoven Manufacturing, and Composite Properties

Polymer Composites, EarlyView.
Comparison of canola fiber reinforced composites manufactured using water‐retted, field‐retted, and enzyme‐treated fibers. ABSTRACT Canola fibers obtained from discarded stalks through various processing methods, including water‐retting and field‐retting followed by mechanical decortication and enzymatic degradation, were utilized as discontinuous ...

Punching Shear Responses of Flat-Plate Assemblages Strengthened with Engineered Cementitious Composites

International Journal of Concrete Structures and Materials
Flat plate flooring systems are susceptible to punching shear failures at slab-column joints, which is pointed out as one of critical obstacles in its application to high-rise buildings in strong wind or seismic regions.

On‐Chip Evaluation of Red Blood Cell Deformability Through Transit Velocity Index in Hematological Diseases

Small, EarlyView.
The deformability of red blood cell is essential for smooth microcirculation. We propose a deformability index using a microfluidic platform with capillary‐like constrictions, based on the relationship between cell deformation and transit velocity through the constrictions. Its effectiveness and clinical potential have been demonstrated in applications

A Hybrid Solid‐State Battery with a Panoramic‐Scale Stack of Bulk Electrodes and a Thin‐Film Electrolyte

Small, EarlyView.
A hybrid all‐solid‐state battery (ASSB) is implemented by integrating a thin‐film electrolyte on a bulk anode, and a thick cathode sheet. A densified anode substrate with suppressed porosity is prepared by cold pressing. Thin‐film electrolyte is fabricated onto the bulk substrate via co‐sputtering and infrared‐based rapid annealing.
