RISModeling of Biaxial Compression Behavior of Carbon Fiber–Reinforced Composite after Low-Velocity Impact
Publisher: ASCE
Abstract: This study presents a finite-element (FE) model considering intralaminar damage and interlaminar delamination to predict the biaxial compression behavior of carbon fiber–reinforced composites (CFRCs) with low-velocity ...
Minimum Distance Calculation Method for Collision Issues in Lifting Construction Scenarios
Publisher: American Society of Civil Engineers
Abstract: In the construction process of prefabricated buildings, collision detection of the tower crane’s lifting path is of paramount importance. During the actual operation of a tower crane, attention is not only given to whether ...
Methods for Calculating Shear Capacity on Oblique Section of Bending Members Strengthened with Enlarged Section
Publisher: American Society of Civil Engineers
Abstract: We infer that several equations currently used to calculate the bearing capacity of an oblique section of a member strengthened with an enlarged section have several mistakes in the specifications for strengthening the ...
Consistent Frame Buckling Analysis by Finite Element Method
Publisher: American Society of Civil Engineers
Abstract: Conventional element assembly process based on the initial configuration of structures does not necessarily imply the satisfaction of compatibility conditions in the deformed state. This may result in a violation to the ...
Stiffness Matrix for Geometric Nonlinear Analysis
Publisher: American Society of Civil Engineers
Abstract: A new stiffness matrix for the analysis of thin walled beams is derived. Starting from the principle of virtual displacements, an updated Lagrangian procedure for nonlinear analysis is developed. Inclusion of nonuniform ...
Joint Rotation and Geometric Nonlinear Analysis
Publisher: American Society of Civil Engineers
Abstract: A geometric stiffness matrix for a beam element has been derived in a related paper. The derived matrix implies quasitangential behavior of bending moments and semitangential behavior of torques. Use of this element matrix ...
Effect of Curvature on Stability of Curved Beams
Publisher: American Society of Civil Engineers
Abstract: This paper intends to derive the nonlinear differential equations of equilibrium for a horizontally curved I‐beam. Based on the principle of virtual displacements, the equilibrium of a bar is established for its deformed ...
Feedback Linearization Tracking Control of Vehicle Longitudinal Acceleration Under Low-Speed Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research addresses the modeling, design, and implementation of a longitudinal acceleration tracking control (LATC) system for a test vehicle at low speeds. An electronic throttle actuator ...
Discussion of “<i>Post‐Buckling Analysis of Steel Space Trusses</i>” by Christopher D. Hill, George E. Blandford, and Shien T. Wang (April, 1989, Vol. 115, No. 4)
Publisher: American Society of Civil Engineers
Effects of Rigid Body and Stretching on Nonlinear Analysis of Trusses
Publisher: American Society of Civil Engineers
Abstract: According to the law of rigid body motion, a body initially acted upon by a set of forces in equilibrium will experience no additional straining when subjected to a rigid body motion, and will remain in equilibrium after ...
