Background:

Multiwalled carbon nanotubes (MWCNTs) possess unique mechanical properties.
Accurate determination of elastic properties is crucial for their applications.

Purpose of the Study:

To investigate the elastic properties of armchair and zigzag MWCNTs.
To develop a simplified finite element model for predicting mechanical behavior.
To establish methods for calculating Young's and shear moduli.

Main Methods:

Utilized a simplified finite element model for MWCNTs.
Simulated tensile, bending, and torsion loading conditions.
Assessed tensile, bending, and torsional rigidities without van der Waals interactions.

Main Results:

Established relationships between rigidities and the diameters of MWCNT layers.
Developed two consistent methods for assessing Young's and shear moduli.
Demonstrated the effectiveness of the nanoscale continuum modeling approach.

Conclusions:

The simplified model provides a benchmark for determining mechanical properties of nonchiral MWCNTs.
The established relationships offer a pathway for predicting elastic moduli.
Nanoscale continuum modeling is a viable approach for MWCNT property assessment.
