We are finding for 2 me´mbers for ADP " Numerical Investigation of Imperfection-Sensitive Buckling in Lattice-Core Sandwich Columns"
- description : Additively manufactured lattice-core sandwich structures inherently exhibit geometric imperfections arising from the manufacturing process. These imperfections significantly influence the global buckling behavior, leading to deviations between idealized analytical and numerical predictions and experimental results.
The objective of this project is to incorporate realistic geometric imperfections into numerical models of FBCC lattice-core sandwich columns and to investigate their effect on global buckling behavior. Analytical and finite element results are compared with provided experimental data in order to assess the predictive capability of the models and to identify the influence of imperfections.
- Task : Creation of finite element models of lattice-core sandwich columns (solid facesheets, beam lattice core)
Implementation of analytical models for global buckling prediction
Modeling and incorporation of geometric imperfections based on experimental data
Comparison of analytical and FEM results with experiments and evaluation of deviations
