Computer Aided Engineering (CAE) systems based on material strength and structural mechanics have already been utilized in the engineering field of structural design, and are expanding their applications to material processing and manufacturing. In the field of heavy and power industries, theoretical backgrounds, analytical investigations and mockup tests together with experiences in actual usage of the components in service have been traditionally referred to for improving the quality and performance of the equipment. In other words, design and feed back of actual usage have been complimenting each other. From the view point of actual experiences, damage mechanisms (e.g. combustion gas corrosion, vibration, over heating, etc) which are difficult to describe in computer algorithm are frequently more important than those incorporated into the widely-used CAE systems. In this paper, some perspectives are described referring to the realistic engineering practices in maintenance and remaining life assessment of high temperature power components together with some expectations for future CAE systems.
