What process limits the strength of ceramics? Write the formula used to calculate the ceramic

strength. Plot the strength distribution curve (i.e., population versus strength) for a typical

ceramic material and explain its shape. Discuss the effects of the following on the reliability of

a ceramic material: (i) increasing its Weibull modulus and (ii) increasing its fracture toughness

without changing its crack sizes (you are required to use a diagram to justify your answer in each

case).
