Elastic and Fracture Behavior of Three-Dimensional Ply-to-Ply Angle Interlock Woven Composites: Through-Thickness, Size Effect, and Multiaxial Tests
Weixin Li, Yao Qiao, Joel Fenner +4
This work presents a comprehensive investigation of the elastic and fracture behavior of ply-to-ply angle interlock three-dimensional woven composites. The research investigated no…
Direct Multilayer Adsorption of Vapor in Solids with Multiscale Porosity and Hindered Adsorbed Layers in Nanopores
Zdenek P. Bazant, Hoang Thai Nguyen
Hindered adsorbed layers completely filling the nanopores must cause significant deviations from the classical BET isotherms for multimolecular adsorption of vapor in porous solids…
Branching of Hydraulic Cracks in Gas or Oil Shale with Closed Natural Fractures: How to Master Permeability
Saeed Rahimi-Agham, Viet-Tuan Chau, Huynjin Lee +7
While the hydraulic fracturing technology, aka fracking (or fraccing, frac), has become highly developed and astonishingly successful, a consistent formulation of the associated fr…
Statistical Extraction of Useful Concrete Creep Data from Imperfect Customary Tests
Mohammad Rasoolinejad, Saeed Rahimi-Aghdam, Zdenek P. Bazant
The reporting and evaluation of creep tests of concrete is complicated by the fact that creep is significant even for the shortest observable load durations. Compared to the strain…
Critique of Critical Shear Crack Theory (CSCT) for fib Model Code Articles on Shear Strength and Size Effect of RC Beams
Abdullah Donmez, Zdenek P. Bazant
The size effect of Muttoni et al.'s CSCT is shown to be very close and asymptotically identical to the energetic size effect law (SEL) extensively verified experimentally and theor…
Fishnet Statistics for Strength Scaling of Nacreous Imbricated Lamellar Materials
Wen Luo, Zdenek P. Bazant
Similar to nacre or brick-and-mortar structures, imbricated lamellar structures are widely found in natural and man-made materials and are of interest for biomimetics. These struct…
Direct Testing of Gradual PostPeak Softening of Notched Specimens of Fiber Composites Stabilized by Enhanced Stiffness and Mass
Zdenek P. Bazant, Viet T. Chau, Gianluca Cusatis +1
Static and dynamic analysis of the fracture tests of fiber composites in hydraulically servo-controlled testing machines currently in use shows that their grips are much too soft a…
Experimental and Numerical Investigation of Intra-Laminar Energy Dissipation and Size Effect in Two-Dimensional Textile Composites
Marco Salviato, Kedar Kirane, Shiva Esna Ashari +2
Design of large composite structures requires understanding the scaling of their mechanical properties, an aspect often overlooked in the literature on composites. This contributio…
Why Fracking Works and How to Optimize It
Z. P. Bazant, M. Salviato, V. T. Chau
Although spectacular advances in hydraulic fracturing, aka fracking, have taken place and many aspects are well understood by now, the topology, geometry and evolution of the crack…
Constitutive Model for Material Comminuting at High Shear Rate
Zdenek P. Bazant, Ferhun C. Caner
The modeling of high velocity impact into brittle or quasibrittle solids is hampered by the unavailability of a constitutive model capturing the effects of material comminution int…
Theory of Sorption Hysteresis in Nanoporous Solids: II. Molecular condensation
Martin Z. Bazant, Zdenek P. Bazant
Motivated by the puzzle of sorption hysteresis in Portland cement concrete or cement paste, we develop in Part II of this study a general theory of vapor sorption and desorption fr…
Theory of Sorption Hysteresis in Nanoporous Solids: I. Snap-Through Instabilities
Zdenek P. Bazant, Martin Z. Bazant
The sorption-desorption hysteresis observed in many nanoporous solids, at vapor pressures low enough for the the liquid (capillary) phase of the adsorbate to be absent, has long be…
