Comparison of Constant-Force Increment and Constant-Rate Loading Protocols in Biaxial Tests of Coated Fabrics
Publisher: American Society of Civil Engineers
Abstract: Biaxial tension testing is an increasingly accepted tool to understand the mechanical behavior of architectural coated fabric membrane materials. However, different loading protocols in biaxial tests result in diverse ...
Investigations of the Mechanical Behavior of Naturally Weathered Envelopes Based on a Long-Term Service Airship
Publisher: ASCE
Abstract: Manufactured with a multilayer functional composite fabric envelope, lighter-than-air (LTA) airships offer a cost-effective approach for payload platforms. Considering the long-term service of LTA airships and their severe ...
In Situ Determination of Stress Distribution of Inflatable Membrane Structure Using Force Finding Method
Publisher: American Society of Civil Engineers
Abstract: Stress distribution on a membrane surface plays a key role in the structural safety and bearing capacity of an inflatable membrane structure, especially for the state under service condition. This paper presents an in situ ...
Initial Configuration and Nonlinear Mechanical Analysis of Stratospheric Nonrigid Airship Envelope
Publisher: American Society of Civil Engineers
Abstract: A stratospheric airship (SSA) is a cost-effective platform for telecommunications and science missions in near space 20 km above the Earth’s surface. However, an accurate model of the structural behavior of the large ...
Composite Carbon–Epoxy Tubes for Space Structures: Ground Vacuum Radiant Experiments and Structural Behavior Analysis
Publisher: American Society of Civil Engineers
Abstract: The utilization of composite carbon–epoxy tubes for space structures, such as antennas and solar arrays, has attracted considerable attention in recent decades due to their high strength-to-weight ratio and multifunctional ...
