Non-propagating fatigue crack lengths were analytically calculated under stress control conditions using plasticity-induced crack closure analysis with the Dugdale model. In addition, a non-dimensionalization method was applied in terms of the Burger

The threshold stress intensity factor range Δ K th was analytically calculated under stress control conditions using the plasticity-induced crack closure analysis with the Dugdale model. Before obtaining Δ K th , the accuracy of the method was veri

Triphenylboron was found to serve as an effective radical initiator for vinyl monomers without any participation of oxygen. The polymerization of methyl methacrylate (MMA) initiated by triphenylboron was studied kinetically in acetonitrile. The over-

It was found that the binary system of tetraphenylborate (TPB) salts and organic acids could serve as radical initiator of vinyl polymerization. From the effects of structures in TPB salts and acids on the polymerization activity, it was concluded th
