 This example demonstrates frictional contact between a solid block and elastic soil in MASTODON. A 6 inch cubic block is centered on top of a 4 foot cubic block of soil. The top surface of the soil is free and the remaining surfaces are fixed in all directions. A uniform normal pressure of 5 psi is applied to the top of the smaller solid block and it is given a prescribed displacement in a direction parallel to the contact surface. The resulting normal and frictional forces at the interface of the two materials are then obtained and compared with analytical results.

 [TensorMechanics](syntax/index.md) kernel is used to set up the stress divergence kernels and [Gravity](syntax/index.md) kernel is used to apply the gravitational force. The [ComputeIsotropicElasticityTensorBeam](syntax/index.md) block is used to create the elasticity tensor of the elastic solid block, using Young's Modulus and Poisson's ratio. The stresses and strain are calculated using [ComputeFiniteStrainElasticStress](syntax/index.md) and [ComputeFiniteStrain](syntax/index.md). The densities are assigned to the solid block and the soil using [GenericConstantMaterial](syntax/index.md).

 The frictional force increases linearly from 0 to 139.123 and remains constant after the block starts sliding. The same behavior is seen in the [frictional_force] obtained from MASTODON.
