Abstract
Adequate support radiuses and weight functions in a MLPG method, were verified first. It is mentioned that accurate solutions are obtained in a MLPG method when support radiuses are set so that the order of a basis vector used in approximating a displacement might agree with the number of overlapping sub-domains at an arbitrary position in a global domain. While, there is the case of being not able to make the order of a basis vector agree with the number of the overlapping sub-domains when symmetrical weight functions are used. In this case, the employment of unsymmetrical weight functions can make the order of a basis vector agree with the number of the overlapping sub-domains. Then static and dynamic analyses of bars were carried out in using the results of the above verification.
