Holonomic Elastoplastic Truss Design using Displacement Based Optimization

Holonomic Elastoplastic Truss Design Using Displacement Based Optimization

Abstract:-

A Displacement Based Optimization (DBO) methodology was connected to truss outline issues with material nonlinearities, to investigate practicality and check effectiveness of the way to deal with take care of such issue. Different truss estimating issues with holonomic (way autonomous) elasto-plastic laws were explored. This sort of material nonlinearity permits us to normally develop the straight flexible truss estimating in the DBO setting to nonlinear issues.

Aerothermodynamic Optimization of Earth Entry Blunt Body Heat Shields for Lunar and Mars Return

Aerothermodynamic Optimization of Earth Entry Blunt Body Heat Shields for Lunar and Mars Return

Abstract :-
A differential evolutionary algorithm has been executed to optimize the hypersonic aerodynamic and stagnation-point heat transfer performance of Earth entry heat shields for Lunar and Mars return manned missions with entry velocities of 11 and 12.5 km/s respectively. The aerothermodynamic performance of heat shield geometries with lift-to-drag ratios up to 1.0 is studied. Each considered heat shield geometry is composed of an axial profile tailored to fit a base cross section.
