Structural Integrity Evaluation of Three-Dimensional-Printed Graphene-Reinforced Polylactic Acid Notched Plates Using Failure Assessment Diagrams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Failure assessment diagrams (FADs) constitute a well-known structural integrity evaluation tool that allows structural components containing crack-like defects to be assessed through a simultaneous analysis of fracture and ...
Analysis of the Difference Between the Reference Temperature Values Derived From Conventional and Mini-C(T) Specimens: Effect of the Number of Valid Fracture Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The long-term-operation of nuclear power plants (NPPs) requires a precise knowledge of the fracture toughness of the reactor pressure vessel (RPV) materials. This property decreases with the irradiation level, ...
Refinements in the Approximate Analysis of Web-Stiffened Sandwich Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Presented in this work is a method of construction of approximate functions in connection with the energy formulation of certain eigenvalue problems of web-stiffened sandwich structures. The ...
On the Possibility of Extending the Crack Length Criterion in the Master Curve Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Master Curve (MC) methodology is a well-known approach utilized to characterize the ductile-to-brittle transition region (DBTR) of ferritic–pearlitic steels. This methodology was initially standardized in ASTM E1921 ...
Validity of Toughness Measurements From Miniature Specimens Failing in Different Fracture Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using miniature compact tension (mini-C(T)) (4 mm thick, 0.16T) specimens to determine toughness in reactor pressure vessel (RPV) steels permits the ductile-to-brittle transition temperature to be derived from small amounts ...
Predicting Critical Loads in U-Notched 3D-Printed Acrylonitrile-Styrene-Acrylate and Carbon Fiber-Reinforced Acrylonitrile-Styrene-Acrylate Specimens Using Failure Assessment Diagrams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The mechanical behavior of three dimensional (3D)-printed polymeric materials, particularly those obtained through fused filament fabrication (FFF), has been extensively investigated over the last few years with ...
Structural Integrity Assessment of the Welded SAE/AISI 1045 Steel for Structural Use
Publisher: ASCE
Abstract: The anchorage of a cable-stayed bridge failed and was subsequently replaced by another anchorage made of SAE/AISI 1045 steel. The new structural component has been assessed by using different options of failure assessment ...
A Rapid Method Connecting Vibrating Structure Size, Piezo-Actuator Size, and Control Voltage for Noise Level Reduction on Oil Drilling Platforms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scientific studies dealing with mechanical vibration attenuation by means of piezoelectric actuators are mostly focused on special details of structure modeling through finite elements and the amount of attenuation that ...
Automatic Directing System for Controlling the Vibration of Frame Structures in Any Horizontal Direction Using a Hybrid Mass Damper
Publisher: American Society of Civil Engineers
Abstract: This paper presents a hybrid system for controlling wind-induced flexural vibration of a frame structure in any vertical plan. The system was implemented and tested in a prototype reduced-scale two-floor building, which ...
