RISRigid-Block DEM Modeling of Mesoscale Fracture Behavior of Concrete with Random Aggregates
Publisher: American Society of Civil Engineers
Abstract: The mesoscale structure generated in concrete plays a significant role in the mechanical properties and local failure behavior of mesoscale concrete. This work proposes a novel rigid-block discrete-element method (RB-DEM) ...
Method for Estimating Normal Contact Parameters in Collision Modeling Using Discontinuous Deformation Analysis
Publisher: American Society of Civil Engineers
Abstract: This paper presents a contact parameter estimation method for collision modeling using discontinuous deformation analysis (DDA). Most DDA codes and discrete element method (DEM) codes use the viscoelastic contact model for ...
Phase Field Characterization of Rock Fractures in Brazilian Splitting Test Specimens Containing Voids and Inclusions
Publisher: ASCE
Abstract: The Brazilian splitting test is a broadly adopted testing procedure for characterizing the tensile strength of natural rock or rock-like material. However, the results of the Brazilian test on specimens with naturally ...
