部分溶込み溶接継手の強度に関する研究

Experimental Studies on the Strength of Welded Joints with Partial Penetration 鷲尾 健三(Kenzo Washio) 滝沢 章三(Shozo Takizawa)

要旨 : 本研究は，部分溶込み溶接の継手強度に関し，従来より不明確なまま残されていた問題点 を明らかにし，設計指針を得ることを意図した実験的研究である。実験は，溶込み量，お よび補強すみ肉のサイズを要因にして行なった。その結果，それぞれの要因が，継手強度 にかなりの影響を与えることを示し，既往の研究と比較しつつ，継手強度を求める実験式 を与えた。さらに，部分溶込み溶接は，すみ肉溶接より高強度が期待でき，かつ，有用な 溶接であることを確めた。 Synopsis :

Lately, the partially-penetrated welding method has received considerable attention. But little information has been available about the strength of welded joints using this method. This paper is intended for clarifying some problems which have remained uncertain, and for suggesting a possible design method. The experiments were conducted on two variable factors amount of penetration and size of fillet welding for reinforcement. The results show clearly that these factors had remarkable effect upon the strength of joints, and the experimental formula has been given by comparing the test-results with the past studies. Generally speaking, it may be concluded from our investigations that the welded joints with partial penetration are stronger than the fillet welded joints and also that the partially penetrated welding is a useful method.

By using the averaging theory of the third order, we show that two is also the maximal number of limit cycles emerging from the period annulus of the unperturbed system

By using the averaging theory of the first and second orders, we show that under any small cubic homogeneous perturbation, at most two limit cycles bifurcate from the period annulus

Assuming the Sobolev regularity of the weightw∈Wl,∞we show that strongly harmonic functions are also inWl,∞ and that they are analytic, whenever the weight is analytic

One of several properties of harmonic functions is the Gauss theorem stating that if u is harmonic, then it has the mean value property with respect to the Lebesgue measure on all

Further, we show that our results are sharp, and in many cases precisely characterize the functions for which equality holds

Furthermore, the following analogue of Theorem 1.13 shows that though the constants in Theorem 1.19 are sharp, Simpson’s rule is asymptotically better than the trapezoidal

Also, we work under a crucial assumption that dictates the memory response in the interior of the domain matches that on the boundary

(4) The basin of attraction for each exponential attractor is the entire phase space, and in demonstrating this result we see that the semigroup of solution operators also admits

Our result indicates that the spread- ing speed coincides with the minimal wave speed of the regular traveling waves

We can also confirm that the spreading speed coincides with the minimal wave speed of regular traveling waves of (1.1), which has been founded in many reaction-diffusion

It is assumed that the restoring force is asymptotically negligible as the solution becomes large, and that the per- turbation tends to zero as time becomes indefinitely large

We have formulated and discussed our main results for scalar equations where the solutions remain of a single sign. This restriction has enabled us to achieve sharp results on

By including a suitable dissipation in the previous model and assuming constant latent heat, in this work we are able to prove global in time existence even for solutions that may

A similar program for Drinfeld modular curves was started in [10], whose main results were the construction of the Jacobian J of M through non-Archimedean theta functions ( !;;z )
