Abstract
This paper presents two examples to the theory and finite element implementation of plasticity. The first example is on the cross-sectional behavior of trapezoidal sheeting subjected to a concentrated load. It is shown that the number of elements (and thus the number of integration points) along the comer radius are important for the correct modeling of this static problem. The second example is on the failure of first-generation sheeting subjected to a concentrated load and a bending moment. This problem, especially for large span lengths, can be solved only with explicit dynamic simulations. These are, for our research field, for the first time published here. The explicit simulations normally function with a rather simple integration scheme for plasticity; is shown that our sheeting results are very sensitive to this.

Cold-Formed Steel Examples to the Theory and Finite Element Implementation of Plasticity
This paper presents two examples to the theory and finite element implementation of plasticity. The first example is on the cross-sectional behavior of trapezoidal sheeting subjected to a concentrated load. It is shown that the number of elements (and thus the number of integration points) along the comer radius are important for the correct modeling of this static problem. The second example is on the failure of first-generation sheeting subjected to a concentrated load and a bending moment. This problem, especially for large span lengths, can be solved only with explicit dynamic simulations. These are, for our research field, for the first time published here. The explicit simulations normally function with a rather simple integration scheme for plasticity; is shown that our sheeting results are very sensitive to this.
