RISNumerical Modeling and Mechanism Analysis of Hybrid Heating and Shock Process for Laser-Assisted Laser Peen Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-assisted laser peen forming (LALPF) is proposed as a hybrid process to combine laser heating and laser peening to improve the bending capability of laser peen forming (LPF) effectively. To predict LALPF-induced bending ...
Variable Damping Profiles Using Modal Analysis for Laser Shock Peening Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The single explicit analysis using time-dependent damping (SEATD) technique for laser shock peening (LSP) simulation employs variable damping to relax the excited model between laser shots, thus distinguishing it from ...
Framework for Seismic Risk Analysis of Engineering Structures Considering the Coupling Damage from Multienvironmental Factors
Publisher: American Society of Civil Engineers
Abstract: Many structures service in complex environments where multiple environmental factors (MEFs) coexist, and the coupling effects of MEFs often aggravate structural damage, thus increasing the risk of structural collapse and ...
Efficient Numerical Solution Method for Large Deformation Analyses of Structures Based on the Updated Lagrangian Formulation
Publisher: ASCE
Abstract: Large deformation analyses of structures are of great importance to the evaluation of structural performance under extreme environmental loads, but currently available methods are time-consuming because of the requirement ...
Modeling the Compressive Buckling Strain as a Function of the Nanocomposite Interphase Thickness in a Carbon Nanotube Sheet Wrapped Carbon Fiber Composite
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Polymer matrix composites have high strengths in tension. However, their compressive strengths are much lower than their tensile strengths due to their weak fiber/matrix interfacial shear strengths. We recently developed ...
