Abstract:To account for both dynamic impact and friction, a general joint interface element is also developed. Here, segment-to-segment contact (SSC) is considered, and contact effects are accounted for along continuous edges of the elements. Thus, micro-scale stick-slip behavior along the joint interfaces can be captured even with a relatively coarse mesh. Numerical examples demonstrate that the general joint interface element is capable of accounting for the friction and impact damping in joint interfaces, capturing the transformation of vibration energy from low frequency to high due to impact, and effectively describing the transient relation between the varying normal pressure and tangential traction.
