Dataset for Computational and Experimental Buckling Analysis of Constant-Stiffness and Variable-Stiffness Composite Cylinders.
DATA IN BRIEF（2024）
Univ Bristol
Abstract
This dataset encapsulates comprehensive information and experimental outcomes derived from the buckling test of variable-stiffness composite cylinders subjected to axial compression. It is the first dataset about the correlation between experimental and computational analysis for a Rapid-Tow Sheared composite cylinder, a recently developed advanced composite manufacturing technique.The data gathered during the test contains: raw test data for force, end-compression and strain gauges; and digital image correlation. The data for finite element validation is for a quasi-isotropic shell and variable-stiffness rapid tow-sheared shell. The data also contain imperfection signatures from a coordinate-measurement machine (CMM) of both cylinders.This compilation of documented data stands as a robust resource for future investigations, enabling comparative analyses, validation of theoretical models, and advancements in the domain of designing and testing composite structures, particularly those employing variable-stiffness manufacturing techniques.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
