METHOD OF EXTRACTING STRESS-STRAIN BEHAVIOR OF MICRO/NANO SCALE STRUCTURE

摘要

PURPOSE: A method of extracting stress-strain relation of micro/nano scale structure is provided to amend an error in the measuring of mechanical property. CONSTITUTION: Load and displacement of a microstructure are experimentally measured. An entry value of a stress-strain is assumed using the measured load and the displacement. The load and displacement are calculated by analyzing a finite-element based on the entry value of the supposed stress-strain. The stress-strain relation is revised using a following equation if it exceeds a preset error range that the load and displacement computed based on the finite-element and the load and displacement experimentally measured. The load and displacement are calculated by a analyzing the finite-element based on revised stress-strain relation.
