Effect of Material Variability on Multiscale Modeling of Rate-Dependent Composite Materials
Publisher: American Society of Civil Engineers
Abstract: The effects of material variability on the mechanical response and failure of composites under high strain rate and impact loading are investigated in this paper. A previously developed strain rate–dependent, sectional ...
Study of Aluminum Alloy 7075-T6 under Ultrasonic Fatigue Loading
Publisher: ASCE
Abstract: A detailed ultrasonic cycle fatigue study has been presented for aluminum alloy 7075-T6 (AA7075-T6) under fully reversed tension-compression loading to investigate the geometric sensitivity, frequency effects, size effects, ...
Optimization Procedure for Design of High‐Speed Prop‐Rotors
Publisher: American Society of Civil Engineers
Abstract: An optimization procedure has been developed to address the complex and conflicting requirements associated with the design of high‐speed proprotor aircraft. Since the key technical issues are maintenance of propulsive ...
Computational Multiscale Analysis of the Mechanical Behavior of Radially Grown Carbon Nanotube Architecture
Publisher: ASCE
Abstract: An atomistically-informed multiscale modeling framework is extended to assess the improvement in mechanical properties of unidirectional fiber-reinforced polymer composites with radially-grown carbon nanotube (CNT) ...
Failure Model for Rate-Dependent Polymer Matrix Composite Laminates under High-Velocity Impact
Publisher: American Society of Civil Engineers
Abstract: A modified Hashin failure model is developed to characterize different failure modes related to high-velocity impact of composite laminates. Hashin’s compressive fiber failure mode has been extended to consider the shear ...
Analytical Solution for Flexural Response of Epoxy Resin Materials
Publisher: American Society of Civil Engineers
Abstract: A piecewise linear parametric uniaxial stress-strain approach has been used to obtain the closed form nonlinear moment curvature response on the basis of strain compatibility in bending for epoxy resin materials. The ...
Characterization of Epoxy Resin Including Strain Rate Effects Using Digital Image Correlation System
