Why is a single-cell model used for crashworthiness analysis?

In this section, the single-cell model is chosen for the investigation of the effects of model parameters on the crashworthiness performance because of its less complexity. Herein, the average of the experimental results will be used as a reference for comparing the obtained results using FE analysis. ...

Can numerical analysis predict crashworthy components?

Numerical analysis results, in terms of global deformations, failures, local accelerations, and biomechanical injuries, have been compared with the experimental ones to assess the prediction capability of the proposed numerical modeling procedure with a focus on improved crashworthy components for certification by analysis future purpose. ...

How to investigate CFRP crashworthiness of a full-scale component model?

Both experimental and numerical studies are popular methods among researchers to investigate CFRP crashworthiness of a full-scale component model and specimen level. Moreover, many studies investigated the combination of CFRP and metal material known as hybrid structure crashworthiness. ...

What are crashworthiness indicators for composite structures?

Specific energy absorption (SEA) and energy absorption (EA) capacity parameters have been frequently cited as the primary indicators in numerous crashworthiness investigations involving composite structures. Table 1. Definition and formulas of crashworthiness indicators used by the majority of researchers for composite structure. ...

What is a crash loading experimental analysis?

These experimental analyses involve subjecting test specimens to various types of loading conditions to understand their behavior and failure mechanisms under crash loading. ...

What is drop testing in crashworthiness testing?

Crashworthiness facility In crashworthiness testing, drop testing is a common experimental method used to evaluate the impact response of structures. This method involves dropping a structure from a predetermined height onto a rigid surface while measuring the response of the structure. ...
