Mission

Advance the state-of-the-art in structural health monitoring (SHM) to improve public safety, reduce maintenance costs, improve readiness, and foster a paradigm shift in design by leveraging and fostering collaborative R&D efforts between academia, industry, and government entities. Provide a means for transferring technology to member companies, agencies, and institutions.

Goals

  • Spur the research and development of new SHM technologies
  • Transfer SHM technologies to member companies to give them a competitive advantage
  • Make PA a hotspot for structural health monitoring, creating a new high tech job market that will provide jobs for residents and draw people and SHM industries to PA
  • Train students to provide an outstanding workforce pool in the SHM technology areas

What is SHM?

Meetings

The Center hosts meetings with the aims of:

  • Bringing designers and owners of platforms that benefit from SHM technology together with researchers and developers of SHM systems
  • Growing the Center by building relationships that lead to fruitful multidisciplinary collaborations between industry, academia, and government

Viewing the meeting presentations requires a USERID and PASSKEY. Contact Cliff Lissenden if you are interested in the Center and viewing the presentations Lissenden@psu.edu

CoE SHM Meeting Programs: August 2011 June 2010 Spring 2009 Fall 2008 Spring 2008 Fall 2007 Spring 2007

The next SHM Meeting will be in June 2012, plan to attend!

SHM Short Course

The Center has developed a 3-day short course on structural health monitoring that is taught at Penn State. Center members can attend the course for free, while others can attend for a registration fee.

Course Objectives: Students will be able to…

  1. describe and compare various types of diagnostics for SHM applications
  2. select a viable SHM methodology for a given application based on available technology
  3. apply the mechanics of guided waves for SHM applications to detect structural defects
  4. analyze vibration data from a complex system and use it to predict remaining fatigue life

Next course offering: 20-22 June 2011

Projects

The first Center funded project, “New Sensors for Improved Ultrasonic Guided Wave Tomography in SHM,” is led by Professor Joseph Rose. The project addresses the need for new, more robust and efficient, sensor technology to enable self diagnostic aircraft structures. Recent development of ultrasonic guided wave tomography and imaging potential for defect detection are leveraged to create new geometric sensor designs. These new sensors enable advancement of physically based defect imaging. Progress reports were given at the Spring 2008 and Fall 2008 meetings. Project Summary

The Siemens membership project, “The Origin of Unpredictability in Damage Evolution Dynamics: Fundamental Limitations on SHM System Performance” is led by Professors Joseph Cusumano and Francesco Costanzo. The project aims to bridge the gap between the microscopic phenomena responsible for damage accumulation, and the macroscopic observables needed for SHM. Acknowledging that true, real-time remaining life predictions will only be as useful as the uncertainty estimates associated with them are sharp, to effectively design next generation SHM systems with true predictive capabilities, we require a fundamental understanding of:

  1. The origin of observed stochasticity in damage evolution processes: how can one explain the probability density functions of macro observables, such as failure times, in terms of microstructural dynamics?
  2. The dimensionality of damage evolution as a function of the fraction of remaining life: what factors determine how much data is needed to make an adequate assessment of life and remaining life?
  3. The sensitivity of damage evolution to uncertainties in the knowledge of initial microstructural states: what are the theoretical limits to the prediction time horizon for remaining life, given a specified degree of accuracy?

A latest Center funded project was conducted in 2009. The project, “Probabilistic Fatigue Life Prediction from Guided Wave Ultrasonic Technology SHM,” was led by Professor Cliff Lissenden. Hwanjeong Cho is the graduate student who worked on the project. The objective is to develop a quantitative guided wave ultrasonic technology that can size a fatigue crack, and autonomously provide input to a prognostic model to predict future fatigue crack size given loading and environmental conditions. Furthermore, the prognostic model must be probabilistic and provide an estimate of the confidence level for the prediction. Work in progress was reported at the June 2009 center meeting and the Quantitative Nondestructive Evaluation conference in July 2009. QNDE Paper
