Compare three nominal stresses using the load actually carried by one plate.
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.
ℓ=e−dh/2; p=F/(dt); τ=F/(2ℓt); σ=F/[(B−dh)t]; Fcompare=min(pa dt,τa 2ℓt,σa(B−dh)t).
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.

1枚の板が実際に受け持つ荷重で、3つの平均応力を比較します。
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。
ℓ=e−dh/2; p=F/(dt); τ=F/(2ℓt); σ=F/[(B−dh)t]; Fcompare=min(pa dt,τa 2ℓt,σa(B−dh)t).
中央に1穴がある平板、端に向かう引張荷重の公称応力モデルです。板は穴の左右で対称です。Fは接合全体ではなく、この板1枚の分担荷重。二股の外板2枚は均等分担を確認した場合だけ各Ftotal/2で計算します。平均面圧にピン径d、正味断面と端抜けには穴径dhを使用します。ピンのせん断・曲げ、隙間による接触分布、疲労、塑性・規格の端距離条件は別に確認します。
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。
Compare three nominal stresses using the load actually carried by one plate.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
ℓ=e−dh/2; p=F/(dt); τ=F/(2ℓt); σ=F/[(B−dh)t]; Fcompare=min(pa dt,τa 2ℓt,σa(B−dh)t).
Nominal-stress model for one centred hole in a symmetric flat plate pulled toward its end. F is the load on this plate, not automatically total joint load. Outer clevis plates use half total load only if equal sharing is established. Bearing uses pin diameter d; net section and tear-out use hole diameter dh. Pin shear/bending, clearance contact, fatigue, plasticity and code edge-distance rules are separate.
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.
図で条件を整理してから計算し、最後に実際の部品仕様を確認します。
Understand conditions with diagrams, calculate, then verify actual specifications.
