WebWe develop a discrete differential geometry-based model of elastic gridshell to investigate their form-finding process. Even though the forward process from 2D footprint to 3D gridshell can be captured by physics-based simulation, the inverse problem of obtaining the original footprint given the 3D deformed shape still lacks a generalized method. WebOct 1, 2024 · Therefore, it is essential to develop a numerical framework that can capture the critical buckling temperature and the vibration response of elastic gridshells in thermal environment. Finite Element Method (FEM) is the most common algorithms to analyze the vibro-acoustic behaviors of thin elastic structures, especially in the low-frequency range.
