Adhesive-bonded composite joint analysis with delaminated surface ply using strain-energy release rate

Chadegani, Alireza; Yang, Chihdar; Smeltzer, Stanley S., III (AMER INST AERONAUT ASTRONAUT, 2012-03)

This paper presents an analytical model to determine the strain energy release rate due to an interlaminar crack of the surface ply in adhesively bonded composite joints subjected to axial tension. Single-lap shear-joint ...
Dynamics and performance of tailless micro aerial vehicle with flexible articulated wings

Paranjape, Aditya A.; Chung, Soon-Jo; Hilton, Harry H.; Chakravarthy, Animesh (The American Institute of Aeronautics and Astronautics, 2012-05-05)

The purpose of this paper is to analyze and discuss the performance and stability of a tailless micro aerial vehicle with flexible articulated wings. The dihedral angles can be varied symmetrically on both wings to control ...
Effect of dents on crack growth in aluminum alloy under constant-amplitude loading

Smith, Bert; Shivally, Praveen; Kumar, Brijesh (AMER INST AERONAUT ASTRONAUT, 2012-03)

The purpose of this study was to determine the effect of dents on the stable crack growth in 0.04-in.-thick 2024-T3 bare aluminum sheet. The test specimens were either pristine, dented, or reworked. The edge-cracked ...
Single Network Adaptive Critic aided nonlinear dynamic inversion for suboptimal command tracking

Lakshmikanth, Geethalakshmi S.; Padhi, Radhakant; Watkins, John Michael; Steck, James E. (IEEE, 2011-09-28)

Using the Approximate Dynamic Programming (ADP) approach, nonlinear optimal control problems can be solved by using a dual neural network architecture called the Adaptive Critic (AC). A Single Network Adaptive Critic (SNAC) ...
Time-varying dynamics of a micro air vehicle with variable-sweep morphing

Chakravarthy, Animesh; Grant, Daniel T.; Lind, Rick (The American Institute of Aeronautics and Astronautics, 2012-05)

In this paper, the longitudinal dynamics of a fast-morphing, variable-wing-sweep micro air vehicle are investigated from a flight dynamics perspective. The time scales over which the morphing occurs are of the same order ...
