# Simulation Quiz 1

### Metal Stamping

Metal stamping is a process where rigid dies are pressed into a metal piece. It is typically used for punching, blanking, embossing, etc. In this exercise, we will investigate what happens when a steel die is inadvertently pushed into an aluminum piece by 0.1 mm. The objective of the simulation is to calculate the force required to make such an indentation (Step 1) and to study the results upon unloading (Step 2).

The die and piece are very long in the out-of-plane direction, so 2D plane strain will be assumed for this exercise, and the geometry is shown below:

1 / 15

Consider a situation where the aluminum piece is defined with only linear elastic material (do not set up and solve such a model). In such a case where there is no plasticity and only linear elastic behavior, which option below can be determined without running the simulation?

2 / 15

Upon unloading (end of Step 2), which statement below best describes the location of the piece relative to the die?

3 / 15

What is the maximum magnitude of force applied to the die to cause the indentation of 0.1mm in the aluminum piece? Select the option that is closest to the result you obtained.

4 / 15

What is the maximum equivalent elastic strain in the piece after indentation (Step 1)? Select the option that is closest to the result you obtained.

5 / 15

Review the Directional Deformation in the X-direction of the aluminum piece. Select the best option that is correct.

6 / 15

Review equivalent elastic strain, equivalent stress, and equivalent plastic strain results. Select the best option that is correct.

7 / 15

Review the Directional Deformation in the Y-direction of the aluminum piece. Select the best option that is correct.

8 / 15

Review the Y-direction Deformation of the aluminum piece at the end of Step 1 (Indentation). The die is moving in the negative Y-direction, but why does some material of the aluminum piece move in the positive Y-direction? Select the best option.

9 / 15

Review equivalent elastic strain and equivalent plastic strain results. Select the best option that is correct.

10 / 15

Consider a situation where the aluminum piece is defined with perfectly-plastic behavior (do not set up and solve such a model). In such a case where the tangent modulus is 0 MPa instead of 500 MPa, which option below can be determined without running the simulation?

11 / 15

12 / 15

Plastic strain and permanent deformation can result when plasticity is included. Select the best option that is a correct statement.

13 / 15
