Smooth Crack Band Model—A Computational Paragon Based on Unorthodox Continuum Homogenization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The crack band model, which was shown to provide a superior computational representation of fracture of quasibrittle materials (in this journal, May 2022), still suffers from three limitations: (1) The material damage is ...
General Fishnet Statistics of Strength: Nacreous, Biomimetic, Concrete, Octet-Truss, and Other Architected or Quasibrittle Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fishnet probabilistic model was recently developed to characterize the strength distribution of nacre-like biomimetic materials. It reveals that the unique fishnet-like connectivity of the material microstructure brings ...
Fishnet Statistical Size Effect on Strength of Materials With Nacreous Microstructure
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The statistical size effect has generally been explained by the weakest-link model, which is valid if the failure of one representative volume element (RVE) of material, corresponding to one link, suffices to cause failure ...

Osmotic Pressure Gradient Effects on Water Diffusion in Porous Rock: Can They Pervert Permeability Tests?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Generation of a large network of hydraulic cracks is of key importance not only for the success of fracking of shale but also for the recent scheme of sequestration of CO2 in deep formations of basalt and peridotite, which ...
Gap Test of Crack-Parallel Stress Effect on Quasibrittle Fracture and Its Consequences
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the standard fracture test specimens, the crack-parallel normal stress is negligible. However, its effect can be strong, as revealed by a new type of experiment, briefly named the gap test. It consists of a simple ...
Smooth Lagrangian Crack Band Model Based on Spress-Sprain Relation and Lagrange Multiplier Constraint of Displacement Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A preceding 2023 study argued that the resistance of a heterogeneous material to the curvature of the displacement field is the most physically realistic localization limiter for softening damage. The curvature was ...
On the Importance of Work Conjugacy and Objective Stress Rates in Finite Deformation Incremental Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with two issues that arise in the finite element analysis of 3D solids. The first issue examines the objectivity of various stress rates that are adopted in incremental analysis of solids. In doing ...
Mode I and II Interlaminar Fracture in Laminated Composites: A Size Effect Study
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This work investigates the mode I and II interlaminar fracturing behavior of laminated composites and the related size effects. Fracture tests on geometrically scaled double cantilever beam (DCB) and end notch flexure (ENF) ...
