In the present study, we found that minor cereal yields in the country were low, mainly due to a lack of modern, high-yielding varieties and improved crop-soil–water management practices. Fracture mechanics was developed during World War I by English aeronautical engineer A. A. Griffith – thus the term Griffith crack – to explain the failure of brittle materials. Griffith's work was motivated by two contradictory facts: • The stress needed to fracture bulk glass is around 100 MPa (15,000 psi). • The theoretical stress needed for breaking atomic bonds of glass is approximately … burke rehab center white plains
