(a) Normalized mode shape of the first mode with a crack location 𝐿₁/𝐿=0.8 and crack depth ratio 𝑎/ℎ=0.4. (b) Normalized mode shape of the second mode with a crack location 𝐿₁/𝐿=0.8 and crack depth ratio 𝑎/ℎ=0.4. (c) Normalized mode shape of the third mode with a crack location 𝐿₁/𝐿=0.8and crack depth ratio a/h = 0.4. (d) Normalized mode shape of the fourth mode with a crack location 𝐿₁/𝐿=0.8 and crack depth ratio 𝑎/ℎ=0.4. (e) Normalized mode shape of the fifth mode with a crack location 𝐿₁/𝐿=0.8 and crack depth ratio 𝑎/ℎ=0.4.
