By using a mechanism based lifetime model, implications for fatigue lives are demonstrated.
Abrasive loading superposed with impact due to abrasive particles are a dominating wear mechanism restricting lifetime in many different industries, for example mining and farming.
To clarify the hydrogen-related vacancy formation mechanism, positron lifetime measurements were performed for Pd1−xAgx alloys that were hydrogenated at 296 or 373 K.
These results justify the consideration of combined damage mechanisms in lifetime assessment.
The aim of the present paper is to understand the nature of damage initiation and propagation in order to lay the foundations for the development of a multi-scale, mechanism-based lifetime prediction model for short fiber reinforced plastics.
Tests have been performed using 4 microstructural states of CMSX-4 (as-received, thermally aged at 1100 °C/300 h and creep deformed in tension at 1100 °C/120 MPa for 24 h and 100 h) to evaluate the impact of microstructure degradation on VHCF fracture mechanisms and lifetime.
For the 1 1 interaction, which can be considered the initial binding event in the case of a sequential binding mechanism, complex lifetimes are significantly reduced.
The effects of package temperature on failure mechanisms and lifetimes under mechanical shock loading were studied with the help of five different types of high-density packages (a WL-CSP and four CSP-BGAs) assembled on both double-layer and multi-layer FR4 boards.
A possible mechanism for EM lifetime enhancement was proposed.
According to the OSPC mechanism, excess electron lifetime should remain constant because the recombination rate is determined by the oxygen adsorption rate.
