The following diagram shows a rectangular plate with a circular hole at the ends. The dimension of the plate is shown in the figure. If the ratio of r/h increase, the stress concentration factor Kt will ______________ Correct Answer decrease

As the ratio r/h increase, there are two possible cases: (i) value of r is increasing–> width of the crack is expanding. (ii) value of h is decreasing –> area of the remaining specimen is decreasing So, both the condition will decrease the severity of crack, and stress concentration factor will increase.
