    • Fracturing in concrete via lattice-particle model 

      Eliás, Jan; Bazant, Zdenek P. (CIMNE, 2011)
      Conference report
      Open Access
      Numerical simulation is used to explore the behavior of concrete beams of different sizes and different notch lengths, loaded in three-point bending. The entire range of notch depth is studied. One limit case is type 1 ...

    • Impact comminution of solids due to local kinetic energy of high shear strain rate: I. Continuum theory and turbulence analogy 

      Bazant, Zdenek P.; Caner, Ferhun Cem (2014-03-01)
      Article
      Restricted access - publisher's policy
      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 into very fine particles. The present objective ...

    • Impact comminution of solids due to local kinetic energy of high shear strain rate: II-Microplane model and verification 

      Caner, Ferhun Cem; Bazant, Zdenek P. (2014-03-01)
      Article
      Restricted access - publisher's policy
      The new theory presented in the preceding paper, which models the dynamic comminution of concrete due to very high shear strain rate, is now compared to recent test data on the penetration of projectiles through concrete ...

    • Microplane model for fracturing damage of triaxially braided fiber-polymer composites 

      Caner, Ferhun Cem; Bazant, Zdenek P.; Hoover, Christian G.; Waas, Anthony M; Shahwan, Khaled W. (2011-04)
      Article
      Restricted access - publisher's policy
      A material model for the fracturing behavior for braided composites is developed and implemented in a material subroutine for use in the commercial explicit finite element code ABAQUS. The subroutine is based on the ...

    • Microplane model M7 for plain concrete: II. Calibration and verification 

      Caner, Ferhun Cem; Bazant, Zdenek P. (American Society of Civil Engineers (ASCE), 2012-11-16)
      Article
      Restricted access - publisher's policy
      The microplane material model for concrete, formulated mathematically in the preceding Part I, is here calibrated by material test data from all the typical laboratory tests taken from the literature. Then the model is ...

    • Multiscale simulation of fracture of braided composites via repetitive unit cells 

      Šmilauer, V.; Hoover, Christian G.; Bazant, Zdenek P.; Caner, Ferhun Cem; Waas, Anthony M; Shahwan, Khaled W. (2011-04)
      Article
      Restricted access - publisher's policy
      Two-dimensional triaxially braided composites (2DTBCs) are attractive in crashworthiness design because their fracture can dissipate a significantly larger amount of impact energy than other light-weight materials. This ...

    • Recent progress in microplane modelling of plain concrete 

      Caner, Ferhun Cem; Bazant, Zdenek P. (CIMNE, 2013)
      Conference report
      Open Access
      Despite determined efforts in mathematical modelling of multiaxial behaviour of plain concrete by many researchers, the existing models have not achieved a full description of this complex behaviour. Among these models, the ...
