Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]
, 1981 One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

In plane Shear Strengthening of Clay Masonry Walls with Opening
Sulaimani Journal for Engineering Sciences, 2020 In this paper, results of testing eight clay brick wall specimens are presented. Seven of the walls contained opening and one wall without opening. The walls were tested under constant uniformly distributed vertical load and gradually increased lateral ...

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Behaviour of reinforced concrete frames with lightweight blockwork infill panels. [PDF]
, 1984 The current investigation concerns the behaviour of lightweight blockork infill panels bounded by reinforced concrete frames. A detailed and comprehensive review of the literature on different frame-inf ill combinations is presented. Details are given

Advanced Engineering Materials, EarlyView.Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

The effects of steel fibre reinforced concrete on system ductility
Materiales de Construccion, 2007 Steel fibre-reinforced concrete is being used extensively today in both field applications and experimental studies on concrete strength and ductility. The state of passive confinement generated by the fibre delays cracking and enhances ductility.

NONLINEAR MULTILEVEL ANALYSIS OF REINFORCED CONCRETE FRAMES
Engineering Structures and Technologies, 2016 Full range analysis of reinforced concrete (RC) members covering the post-crack and post-peak regimes is important for obtaining the deformation response and failure mode of structural members. When a RC member is subject to an increasing external load, the critical sections would exhibit cracking and/or softening.

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
