文摘
- •
Finite strain thickness-extensible shell with two parameters for an independent upper/lower shell face motion.
- •
Assumed strain reproduction of the in-plane bending modes without additional degrees-of-freedom using least-squares fit.
- •
Exact director inextensibility, with consistent linearization.
- •
High coarse-mesh accuracy (quantified by demanding benchmarks, including recent papers on shells).
- •
Quantified low mesh distortion sensitivity with respect to the alternatives.
