Find average direct-shear stress from effective weld length and equal-leg fillet size.
Click the grid to add ordered vertices. Edit coordinates in mm; separate holes with a blank line. The last vertex closes to the first automatically.
Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.
Reference calculation only. Results do not certify suitability for an actual design or its safety.
Inputs: select a blue symbol to edit Results: red-orange values and lines
3D shows an illustrative extrusion. Its display length does not enter the section calculations. Edit dimensions in 2D.
a=z/√2; Aw=nLa; τ=F/Aw; Fcompare=τallow Aw.
Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.
ReferenceEquations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.
Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.
Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

有効溶接長さ・脚長から、偏心のない直接せん断の平均応力を求めます。
選択した形状・計算方法により、使う項目は変わります。実際の計算は上の図と入力欄で行えます。
a=z/√2; Aw=nLa; τ=F/Aw; Fcompare=τallow Aw.
90°等脚すみ肉で、全溶接線ののど断面が直接せん断を等分担するモデルです。有効長さLと許容応力は適用する材料・施工・規格から入力します。偏心による曲げ・ねじり・剥離、母材、欠陥、疲労、最小脚長や端部低減は含みません。
現在選択中の方法には、操作欄の「計算式・適用条件」を使ってください。参考計算であり、設計全体の安全性を保証するものではありません。
Find average direct-shear stress from effective weld length and equal-leg fillet size.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
a=z/√2; Aw=nLa; τ=F/Aw; Fcompare=τallow Aw.
90° equal-leg fillets with uniform direct shear shared by the effective throats. Enter effective length and an allowable stress appropriate to material, workmanship and governing specification. Eccentric bending/torsion/peel, parent material, defects, fatigue, minimum sizes and end reductions are excluded.
The displayed formula and conditions in the working panel apply to the currently selected model. Reference calculation only; it does not certify a complete design.
