Phase transitions in 2D multistable mechanical metamaterials via collisions of soliton-lik

Matlab code for numerical simulations of phase transitions in 2D multistable mechanical metamaterials composed of rotating squares. The code includes modules for simulating transitions induced by quasistatic loading and by collisions of soliton-like pulses. The code was authored by Weijian Jiao and is available under an Open Access license.

Use Cases

• Simulating quasistatic phase transitions in 2D multistable metamaterials based on the provided 'Main_code_phase_transition_quasistatic' module.
• Simulating dynamic phase transitions induced by soliton-like pulse collisions based on the 'Main_code_phase_transition_collisions' module.
• Studying the behavior of rotating square unit cells in mechanical metamaterials under different loading conditions.
• Validating theoretical models of multistability and nonlinear wave propagation in designed material structures.

Strengths

• Code is specifically designed for two distinct simulation scenarios: quasistatic loading and dynamic pulse collisions.
• The dataset is associated with a research concept (phase transitions in 2D multistable metamaterials) described in the title and description.
• Available under an Open Access license, facilitating reuse and modification.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
