Abstract: Concrete is a complex heterogeneous material. Its internal structure controls its mechanical behavior through crack localization, branching, and coalescence. As a result, only models that represent its failure through ...

Abstract: The first experimental campaign presented in the preceding Part I of this study is used to calibrate and validate a comprehensive computational framework called the lattice discrete particle model for fiber-reinforced ...

Abstract: Modern structural design relies heavily on accurate numerical simulations of materials and structures. For concrete and RC, however, available computational models, although successful for many applications, fail to a large ...

Abstract: Ultrahigh performance concrete (UHPC) is a special class of cementitious composites with superior strength and durability characteristics. Typically, UHPC contains very fine aggregate (size less than 1 mm) and short ...

Abstract: Time-dependent deformations, including creep and shrinkage, are essential factors that govern multiple design aspects of prestressed/post-tensioned concrete structures. These include (but are not limited to) time to initial ...
