Highlights
Shear-Deformable Phase-Field Fracture Framework
This study develops a consistent phase-field framework for dynamic ductile fracture in curved shells. It integrates transverse shear deformation, plane-stress plasticity, and coupled geometric and material nonlinearities within a robust shell formulation.
Numerical Benchmarks and Fracture Predictions
Numerical benchmarks reproduce published fracture responses under static and dynamic loading. The framework captures crack initiation, propagation, curving, branching, and crack-tip velocities in thin and moderately thick shells.

Highlights
Stability-Preserving Load Regulation (SPLR) for Thermomechanical Buckling
To resolve numerical instabilities in conventional buckling analyses, this study introduces the SPLR scheme. This maintains the positive definiteness of the stiffness matrix throughout the optimization process and suppresses complex eigenvalues, ensuring reliable and physically meaningful buckling evaluations.
Multimaterial Topology Optimization and RACM Application for Shells
The Refined Adaptive Continuation Method (RACM) is extended to multimaterial systems to enhance convergence and numerical robustness. Furthermore, using the MITC4 element eliminates shear locking, thereby optimizing the thermomechanical buckling performance of complex curved shell structures.

Highlights
Development of the Partition of Unity-based Four-node Tetrahedral Element
The paper introduces TET4E, a refined element using the Partition of Unity method to enrich displacement fields and eliminate volumetric locking in nearly incompressible materials. It integrates Mooney-Rivlin and Neo-Hookean models within a Total Lagrangian framework to accurately handle large deformations without adding nodes.
Nonlinear Modal Analysis and Numerical Validation
This study validates TET4E using a new iterative procedure for nonlinear modal analysis to capture amplitude-dependent frequencies and mode shapes. Numerical examples, such as soft robots and distorted plates, demonstrate its superior accuracy and convergence over traditional elements, even with coarse meshes.

Highlights
Phase-Field Modeling for FGM Thermal Fracture
This paper presents a phase-field model to analyze thermal-mismatch fracture behavior in functionally graded materials (FGMs). By homogenizing fracture resistance via the rule of mixtures , the model accurately captures complex experimental crack patterns in bi-material plates, showing better agreement with experimental data than theoretical models.
Crack and Energy Evolution in Various Plate Shapes
The validated model is applied to investigate thermal fractures in circular, square, and triangular FGM plates. It provides a fundamental understanding of fracture mechanisms by analyzing three key aspects: damage fields for crack propagation, principal stress fields in fracture-critical regions, and energy evolution during deformation.
