Why Toughness Of Ductile Materials Is Higher Than Brittle Materials? Because the area under the stress-strain curve for the ductile material above is larger than the area under the stress-strain curve for the brittle material, the ductile material has a higher modulus of toughness — it can absorb much more strain energy before it breaks.
What Happens Ductile Deformation? Ductile deformation involves the production of large, open folds in the sediments or rocks in front of an advancing glacier, which may develop into overfolds or begin to undergo internal thrusting due to continued ice advance. What happens to a material during ductile deformation? When rocks deform in a ductile manner,
Which Rock Is More Likely To Break Under Stress? Composition—Some minerals, such as quartz, tend to be brittle and are thus more likely to break under stress. Other minerals, such as calcite, clay, and mica, tend to be ductile and can undergo much plastic deformation. In addition, the presence of water in rock tends to
