Hi, So basically I am wondering how can you increase damping within a part, just by altering its geometry. I've researched this topic, but haven't yet found anything significant. Here are my main findings: - Rayleigh Damping uses the equation: [C] = α[M] + β[K], which to me shows that mass and stiffness affect damping - Damping constants are difficult to obtain; use of available literature and experimentation are the only ways to go From this, I believe there is a useful link between stiffness and damping, and that I could design a part in certain ways to increase damping/reduce vibration (I understand these are very different things). For example, would stiffening a part, reduce the response of the part under excitation? The aim for me is to develop an understanding from a design perspective as to how we can use geometry to reduce stresses in a part under dynamic loading. Thanks in advance for any help.
