Study on the Influence Mechanism of the Void Structure on the Directional Propagation of Cracks Induced by High-Voltage Electric Pulses

Key Points

• Crack propagation is significantly influenced by the void structure present in the material, impacting its longevity.
• The study identified key mechanical properties that affect how cracks spread when subjected to high-voltage electric pulses.
• Analysis reveals a relationship between stress distribution and crack propagation directions influenced by void structures.
• Understanding these dynamics may lead to improved designs in materials exposed to electrical stresses, enhancing safety.
