RISLocal Damage Evolution of Double Cantilever Beam Specimens During Crack Initiation Process: A Natural Boundary Condition Based Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cohesive zone models are being increasingly used to simulate fracture and debonding processes in metallic, polymeric, and ceramic materials and their composites. The crack initiation process as ...
Thermoviscoplastic Modeling and Testing of Shape Memory Polymer Based Self-Healing Syntactic Foam Programmed at Glassy Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditionally, programming of shape memory polymer (SMP) material requires initial heating above the glass transition temperature (Tg ), subsequent cooling below Tg and removal of the applied ...
Thermomechanical Characterization of Shape Memory Polymer–Based Self-Healing Syntactic Foam Sealant for Expansion Joints
Publisher: American Society of Civil Engineers
Abstract: The failure of expansion joints is a leading cause for structural damage to bridge decks and concrete pavements. A fundamental requirement for sealant is that it should always apply a compressive stress to the concrete ...
Fire Behavior of Prestressed Stayed Columns: Critical Temperature and Mode Transition
Publisher: ASCE
Abstract: Prestressed stayed columns are vulnerable to the stiffness loss in fire. This study aims to reveal the fire resistance and failure behavior of this system. Based on the theoretical optimum prestress, the fire behavior of ...
Mechanical Properties of Superhigh-Strength Q960 Steel at Elevated Temperatures Considering the Tensile Strain Rate
Publisher: American Society of Civil Engineers
Abstract: This investigation delves into the impact of temperature and tensile strain rate on the mechanical characteristics of high-strength Q960 steel. The inherent strength and stiffness properties of steel undergo degradation ...
On Approximately Realizing and Characterizing Pure Mode-I Interface Fracture Between Bonded Dissimilar Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bimaterial systems in which two dissimilar materials are adhesively joined by a thin adhesive interlayer have been widely used in a variety of modern industries and engineering structures. It ...
Shape Memory Polymer-Based Sealant for a Compression Sealed Joint
Publisher: American Society of Civil Engineers
Abstract: In this paper, the authors report a case study of synthesis, fabrication, programming, installation, and performance monitoring of a shape memory polymer (SMP) based smart sealant for compression sealed joint in a concrete ...
Elastic Modulus Prediction of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: The distresses of asphalt pavement, which include fatigue, rutting, and low temperature cracking, are related to the elastic modulus of asphalt concrete (AC). In addition, the elastic modulus of AC is a design variable for ...
Investigation into Waste Tire Rubber-Filled Concrete
Publisher: American Society of Civil Engineers
Abstract: Over the years, there has been mounting interest in the use of recycled tire rubbers in highway construction. Tire rubber-filled concrete, a rubberized Portland cement concrete with a portion of aggregates replaced by tire ...
Behavior of Thermoset Shape Memory Polymer-Based Syntactic Foam Sealant Trained by Hybrid Two-Stage Programming
Publisher: American Society of Civil Engineers
Abstract: Recently, a shape memory polymer-based self-healing syntactic foam was proposed and tested as a sealant for expansion joints. The key for success is to train the foam by using a two-dimensional (2D) stress condition ...
