Learning Objective
• Define a ductile


节选段落二：
An element deletion criterion is defined and therefore the plate ruptures and allows the
ball to pass through.

o Ball
▪ Modulus: 210,000 MPa
▪ Poisson’s: 0.3
▪ Density: 7.8e-9 Tonnes/mm3
o Plate
▪ Modulus: 70,000 MPa
▪ Poisson’s: 0.3
▪ Density: 2.5e-9 Tonne/mm3
▪ Plastic Properties:
