Influence of particle morphology on 3D kinematic behavior and strain localization of sheared sand
( American Society of Civil Engineers (ASCE) , 2017 , Article)The constitutive behavior of sheared sand is highly influenced by particle morphology, gradation, mineralogy, specimen density, loading condition, stress path, and boundary conditions. The current literature lacks a ... -
Effect of crushable blockouts on a full-scale guardrail system
( Taylor and Francis Ltd. , 2017 , Article)Since the performance of the guardrail system depends in part on the compatibility of vehicle-to-roadside hardware, it is important to improve the interaction of the vehicle with the guardrail system by adding more compliance ... -
Optimization of linear zigzag insert metastructures for low-frequency vibration attenuation using genetic algorithms
( Academic Press , 2017 , Article)Vibration suppression remains a crucial issue in the design of structures and machines. Recent studies have shown that with the use of metamaterial inspired structures (or metastructures), considerable vibration attenuation ... -
Simulation-Based Condition Assessment Model for Sewer Pipelines
