Abstract: “Numerical modeling of Casagrande cup test can be conductedby applying Newmarks method in a finite element program.Casagrande is a test that applies acceleration as a load to minislope that is molded in a cup until the slope fails. Modeling of the test cannot be performed without scaling because finite element program must have its limit in mesh size. Thus, a series of scaling up and down needs to be carried out to match the parameter for obtaining a realistic result. The test is done in a series of water contents to gain information about the change in behavior of the slope, which is then validated by the result of a physical test, on which the input for the modeling data is gained. By doing so, the difference in real test and modeling result can be equally compared.This study aims to propose a method of modeling the Casagrande cup test, which includes the scaling procedure and the reduction in Youngs modulus to obtain the desired result. In conclusion, reduction in Youngs modulus of t”
