What is Habibie Theorem?
What is Habibie Theorem?
Habibie later developed the crack propagation theory, earning him the name ‘Mr. Crack’ from his international colleagues. Through his theory, the crack points could be predicted early, resulting in safer aircrafts, reducing the risk of sudden failure, and making their maintenance cheaper and easier.

What is crack theory?
The Griffith theory states that a crack will propagate when the reduction in potential energy that occurs due to crack growth is greater than or equal to the increase in surface energy due to the creation of new free surfaces. This theory is applicable to elastic materials that fracture in a brittle fashion.

What are the three modes of fracture?
Modes of fracture refers to the decomposition of crack tip stresses into three loadings, or “modes.” The modes are Mode-I (stress orthogonal to the local plane of the crack surface), Mode-II (stress parallel to the crack surface but orthogonal to the crack front), and Mode-III (stress parallel to the crack surface and …
What are the 3 modes of fracture toughness?
2. Materials and Methods
- 2.1. SCB Specimens and Calculation of Mode I Fracture Toughness. In fracture mechanics, there are three types of fracture: mode I (tensile fracture), mode II (shear fracture), and mode III (out-of-plane tearing fracture) [20–29].
- 2.2. Sample Preparation.
How did Suharto gain power?
During the Japanese occupation of Indonesia, Suharto served in Japanese-organised Indonesian security forces. The army subsequently led an anti-communist purge and Suharto wrested power from Indonesia’s founding president, Sukarno.
