RISA Representation of Anisotropic Creep Damage in Fiber Reinforced Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A creep damage model is presented that allows for anisotropic distributions of damage in composite materials. An earlier model by the writers allowed for anisotropic damage growth rate but, ...
Effects of State Recovery on Creep Buckling Under Variable Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural alloys embody internal mechanisms that allow recovery of state with varying stress and elevated temperature; that is, they can return to a softer state following periods of hardening ...
The Measurement of Dynamic Strains Using Birefringent Strips
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study is presented of the bonded birefringent strip as a means of observing transient deformations on the surfaces of opaque bodies. The particular situation investigated consists ...
Model of Viscoplasticity for Transversely Isotropic Inelastically Compressible Solids
Publisher: American Society of Civil Engineers
Abstract: A transversely isotropic, viscoplasticity model is formulated as an extension of Bodner's model. Account is made of inelastic deformation that can occur in strongly anisotropic materials under hydrostatic stress. The ...
Creep Model for Metallic Composites Based on Matrix Testing
Publisher: American Society of Civil Engineers
Abstract: An anisotropic creep model is formulated for metallic composites with strong fibers and low to moderate fiber volume percent
Time Dependence in Biaxial Yield of Type 316 Stainless Steel at Room Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes two biaxial experiments which investigated time and rate effects in the yield and deformation behavior of type 316 stainless steel at room temperature. The first experiment ...
Optimal Fiber Orientation in Locally Transversely Isotropic Creeping Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approximate method is developed for comparing various fiber configurations in a composite structure with the objective of achieving optimal resistance to creep failure. The class of composite ...
Creep of Polymer Matrix Composites. II: Monkman-Grant Failure Relationship for Transverse Isotropy
Publisher: American Society of Civil Engineers
Abstract: This research concerns polymer matrix composite (PMC) materials having long or continuous reinforcement fibers embedded in a polymer matrix. The objective is to develop comparatively simple, designer friendly constitutive ...
Creep of Polymer Matrix Composites. I: Norton/Bailey Creep Law for Transverse Isotropy
Publisher: American Society of Civil Engineers
Abstract: This research concerns polymer matrix composite (PMC) materials having long or continuous reinforcement fibers embedded in a polymer matrix. The objective is to develop comparatively simple, designer friendly constitutive ...
Creep Buckling of Cylindrical Shell under Variable Loading
Publisher: American Society of Civil Engineers
Abstract: The ability for structural alloys to exhibit recovery of state, i.e., return to a softer state following periods of hardening, under varying stress and temperature is known to strongly influence structural response under ...
