Syllabus Description

Notes collected from MANE 6962: Experimental Mechanics, from the fall of 2018.

Experimental mechanics with Dr Mills covered a variety of practical engineering topics such as AFM, photoelasticity, and Hertzian contact mechanics. Manual image tracking and time dependent strain measurements covered in final projects using ncorr.

Summary from course catalog

In this course we will study the design and analysis of experiments in solid mechanics including some applications in biomechanics. Methods for experimental stress analysis and the mechanical testing of materials will be discussed. Measurement techniques including instrumentation and data acquisition for key mechanical parameters such as displacements and forces (point and full-field measurements). Mechanical behaviors include creep and relaxation, high strain rate, fracture, fatigue, and aspects of biological soft tissues.
