12th Annual Conference of Society for Structural Integrity and Life (DIVK12) Forecasting behaviors of tubular designs in marine transportation structures: Effect of mesh variations in nonlinear FE approach Muhammad Daffa Alifianto a , Aditya Rio Prabowo a, *, Hermes Carvalho b,c , Bo Cao d , Ristiyanto Adiputra e a Department of Mechanical Engineering, Universitas Sebelas Maret, Surakarta, Indonesia b Department of Structural Engineering, Federal University of Minas Gerais, Belo Horizonte, Brazil c Department of Structural Engineering and Geotechnical, University of São Paulo, Brazil d China Shipbuilding Industry Corporation Economic Research Center, Beijing, China e Research Center for Hydrodynamics Technology, National Research and Innovation Agency, Surabaya, Indonesia Abstract This study was conducted to determine the response of sandwich panels to impacts involving forces on the sandwich panels. With axial compression research on sandwich panels. Collision accidents in marine transportation can be fatal, so research is needed to improve the safety of ship structures, especially sandwich structures, because previous studies have studied more hollow tubes than sandwich panel tubes. Therefore, this study is significant because many still need to study sandwich panels. This study uses the Abaqus application with axial compression analysis, using an impactor as a sandwich panel compression suppressor with a diameter of 96mm and a height of 180 mm. The sandwich panel designed in ABAQUS uses dimensions of an outer diameter of 80 mm, an inner diameter of 60 mm, and a height of 200 mm with Mild Steel material. It uses mesh variations as a benchmark for the success of this simulation. From the results of the simulation carried out using ABAQUS software, the difference between mesh variations can be seen from the results shown, namely, the smaller the mesh used, the greater the force and time required. © 2026 The Authors.
