Sample interview questions: How do you assess and analyze the failure or degradation of materials in your research?
Sample answer:
Assessing and analyzing the failure or degradation of materials in my research involves a systematic approach that combines experimental techniques, theoretical models, and advanced characterization tools. Firstly, I would conduct a thorough investigation of the failed or degraded material, examining its physical, chemical, and mechanical properties. This initial assessment often involves visual inspection, microscopy, and spectroscopic techniques to identify any visible signs of damage, such as cracks, fractures, or surface changes.
Next, I would use various testing methods, such as mechanical testing, thermal analysis, and spectroscopy, to evaluate the material’s performance under different conditions. This helps in understanding how the material behaves under stress, temperature fluctuations, and exposure to different environments. Mechanical testing involves subjecting the material to controlled loads and measuring its response, enabling the identification of any weaknesses or structural defects that may have led to failure.
To analyze the underlying causes of material failure or degradation, I would employ theoretical models and simulations. These models can predict the behavior of materials under specific conditions, providing insights into the failure mechanisms and potential areas of improvement.
