Challenge Problems
Push your limits with advanced challenges
A structural beam made of a ductile material is subjected to increasing loads. Analyze at which load condition it transitions from elastic to plastic behavior and what consequences that may have in design.
💡 Hint: Focus on how yield point values are used in engineering safety factors.
During a test, a glass panel is subjected to a static load beyond its elastic limit. What can be expected in terms of stress distribution and failure? Discuss the implications.
💡 Hint: Remember the stress-strain behavior of brittle materials during excessive loading.
