- Abstract
- Methods and principles of complex analysis for determining or refining the bearing capacity or ultimate strength of composites using additional registration systems for ambiguous diagrams are considered. The hypothesis for clarification of the material strength limit based on complex (cross-sectional) analysis of composite materials was modified and specified. A hypothesis on the existence of a "critical value of cumulative acoustic emission energy" - a sound-energy analog of strength - was put forward and substantiated.
