However, this does not bear any final result or any high level engineering.
Summary Advanced Space Launch mechanism can be the best option for the future launch mechanism.
Advanced space launch is spaceport itself which is great advantage over the current mechanism.
This advanced mechanism will reduce the cost of launching with less impact on the environment.

The basic idea was to establish a periodical international forum for multiscale approaches in fatigue and fracture of materials in the middle of Europe.
Therefore, respective sections focused on atomistic models, models based on crystal defects, numerical and statistical continuum models, advanced experimental methods and relationships between microstructure and mechanical properties appeared during the MSMF-2 conference in 1998.
It is my pleasure to thank the editorial board of the journal Key Engineering Materials for the readiness to publish this volume devoted to MSMF-6.

The aim of the conference is to bring together the expertise of scientist and engineers from  universities and industry in the field of Structural Health Monitoring, Non-Destructive Evaluation, and  Condition Monitoring. 
Due to  interdisciplinary character of SHM systems, the conference brings together experts from area of  mechanics, materials engineering, electronics, software engineering, and signal processing as well as  system users from civil engineering, aviation, power plants, wind turbines, chemical plants,  petrochemical plants and railways sectors. 
A significant part of the conference is dedicated to  utilization of advanced measurement techniques, signal processing, and computation methods.  
The Smart Diagnostics conference is established as a international forum for discussion and  dissemination of recent advances in damage detection, localization, assessment, and safe life  prognosis of many different structures.
