Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

open access: yesAdvanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Progressive collapse susceptibility of a long span suspension bridge [PDF]

open access: yes, 2013
Long span bridges are complex structural systems, often having strategic roles in the network infrastructures; consequently, their susceptibility to a disproportionate response in case of local failures needs to be assessed.

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Assessment of progressive collapse of steel structures under seismic loads

open access: yesAlexandria Engineering Journal, 2018
Progressive collapse involves a series of failures that lead to partial or total collapse of a structure. It is generally initiated by loss of one or more vertical load carrying elements.

Progressive collapse assessment of precast prestressed reinforced concrete beams using applied element method

open access: yesCase Studies in Construction Materials, 2020
Due to the repetitive progressive collapse events, it became necessity to form theories of designs against those cases of loadings. Prestressed reinforced concrete elements become widely used in construction field due to various properties that ...

Keruntuhan Progresif Gedung Beraturan Sistem Ganda [PDF]

open access: yes, 2017
This research aimed to examine the progressive collapse of dual system building structures due to the loss of one or more structural elements that lead to successive collapse of other elements.

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Theoretical and experimental research on progressive collapse of RC frame buildings [PDF]

open access: yesUrbanism. Arhitectura. Constructii, 2013
Progressive collapse of the buildings has become an important issue to be studied in recent years due to the catastrophic nature of its effects. This subject can be approached from two different perspectives: one where an ideal collapse of the structure ...

Reviving egalitarianism in the Global Transformation: Building occupational security [PDF]

open access: yes, 2008
The world is in the midst of a Global Transformation, reflecting the painful creation of a global market society. Globalization was the disembedded phase, in which inequalities and insecurities multiplied as national systems of regulation, social ...

Implementation of Drug‐Induced Rhabdomyolysis and Acute Kidney Injury in Microphysiological System

open access: yesAdvanced Functional Materials, EarlyView.
A modular Muscle–Kidney proximal tubule‐on‐a‐chip integrates 3D skeletal muscle and renal proximal tubule tissues to model drug‐induced rhabdomyolysis and acute kidney injury. The coculture system enables dynamic tissue interaction, functional contraction monitoring, and quantification of nephrotoxicity, revealing drug side effect‐induced metabolic ...
