Stress Analysis of the Glass Cup in the Process of Falling Based on the Finite Element Method

In order to study the stress distribution and the maximum stress of the glass cup in different drop heights and different drop ways, the mechanical properties of glass during falling process was analyzed based on the finite element method. The results show that as the drop height increases, the stress of the glass cup will gradually increase and the stress distribution area will broaden. When the stress reaches the maximum, the glass cups will be broken. Due to diverse drop ways, the stress and the stress distribution area of the glass cup is different, and the stress distribution area is not proportional to the drop angle of the glass cup.
