Phase-field: Compact specimen#

In this section, the specimens described in Wagner[1] are simulated using the phase-field model proposed in the referenced work.

Four simulations are conducted, each with distinct configurations:

Specimen configurations with varying initial crack positions (H) and hole presence.#
