Numerous austenitic stainless steels and nickel-based alloys are power hardening materials, which is widely used in key structural materials of nuclear power plants.
Therefore, the re-distribution of stress and strain at the growing crack tip in power hardening materials will be discussed by using ABAQUS software in this paper, which provides a foundation for quantitative predicting environmentally assisted cracking growth rate in key structural materials of nuclear power plants.
The numerical simulating test process satisfied American Society for Testing and Materials (ASTM) E399 standards.

Building Materials Composition Influence to Sound Transmission Loss (STL) Reduction Erni Setyowati1,a, Anggana Fitri Sadwikasari2,b 1Building Science Laboratory, Engineering Faculty, UNDIP, Semarang, Indonesia 2Islamic University of Indonesia (UII), Yogyakarta, Indonesia aernisyahdu@gmail.com, banggana@gmail.com Keywords: Airport noise, building material composition, STL reduction.
The development of the airport always causes the noise impact to the surrounding environment.1 Housing close to the airport will be annoyed by the aircraft noise, especially if the building is not added by absorber building materials.
The decrease of the noise level found out from the research is caused by the value of Sound Transmission Loss (STL) of the building materials composition.
In some journals that I wrote that the building models are not assumed to be a single model.
