Second order sensitivity analysis for shape optimization of continuum structures
This study focuses on the optimization of the plane structure. Sequential quadratic programming (SQP) will be utilized, which is one of the most efficient methods for solving nonlinearly constrained optimization problems. A new formulation for the second order sensitivity analysis of the two-dimensional finite element will be developed. All the second order required derivatives will be calculat...
متن کاملSecond Order Surface Analysis
Results from analyzing the curvature of a surface can be used to improve the implementation, e ciency, and e ectiveness of manufacturing and visualization of sculptured surfaces. In this paper, we develop a robust method using hybrid symbolic and numeric operators to create trimmed surfaces each of which is solely convex, concave, or saddle and partitions the original surface. The same method i...
متن کاملRoughening transition of prism faces of ice crystals grown from melt under pressure
By observing the crystal shapes and kinetics of ice Ih growing at high pressures from the melt, it was found that the prism f1 0 1̄ 0g faces undergo a roughening transition at approximately 16 C and 160MPa (1600 bar) in H2O ice, and 14 C and 180MPa (1800 bar) in D2O ice. At temperatures above the roughening transition, the prism facets completely vanished and the curves of growth rate versus gro...

متن کاملDEVELOPING A FORMULA TO REPRESENT THE SECOND-ORDER WAVE EFFECTS ON MOORED FLOATING STRUCTURES
The effects of wave direction, frequency and the waterline shape of floating structures on the wave mean drift force formula have been considered separately by several authors but there isn't a general formula to take into account all of these effects. In this regard, Faltinsen’s wave drift force formula has been modified by adding finite draft coefficient. The results obtained from this formu...
