Vibration of Circular Plates with Mixed Edge Conditions. Part II: Numerical Determination for Higher Frequencies

Main Article Content

ยศ สมพรเจริญสุข


The main goal of this research is to numerically deal with an accurate value for some higher natural frequencies represented in terms of frequency parameter of circular plates using finite element software with a dense meshed of element model. Two different cases of vibratory circular plate regarding mixed edge conditions are considered as (i) simply supported-free and (ii) clamped-free. The obtainable numerical results are given and presented as a dependent function of the angle over the circumferential plate sup-porting. The values for the first thirty frequency parameters are then carried out and numerically given in the tabular forms, which could be served for comparison with other methods. Some observations and limitations are also addressed.
