Lifetime and Reliability

The focus of lifetime and reliability is on the characterization of damage mechanisms in production as well as on lifetime predictions for products made of special materials and material combinations. Therefore, it is necessary to combine different methods: Experimental measurement and testing Fractography Statistical analysis Mathematical simulation This tool box provides the basis for problem solving in production processes as well as for the development of new products.

Example 1: Bursting Bursting measurement of pharmaceutical products for the determination of failure probability.

Example 2: Hardness Indentation methods for determination of hardness (Knoop, Vickers, Martens) and elasto-plastic properties (elastic moduls, plastic and elastic work) of glass, glass- ceramics and ceramics.

Example 3: Simulation Mathematical simulation of a hot-forming process for sealing glass fibers with metal rings.

Analytical methods Static strength, tension-compression (uniaxial), bending (2pt., 3pt., 4pt., ring-on-ring), bursting (hydrostatic) Dynamic strength, notch test, DCDC (crack growth), thermal shock, climate testing Fractography, crack origin, fracture mirror, stress-optical measurements Statistical analysis of strength data Indentation measurements (Knoop, Vickers, Martens), micro- and nano-hardness, fracture toughness, crack initiation load, elastic and plastic indentation Hydrogen absorption by getter materials FEA calculations
