Box Compression Test (BCT) = k1 ∗ ECT × √h ∗ Z Reference Mckee formula (simplified version) Where: k1 = a constant value of 5.87 h = Corrugated FiberBoard (CFB) thickness (inches) Z = box perimeter (inches) = 2(L + W) NOTES English units are used because CT Values are typically in pounds per inch units.

Overall, the box compression strengths (BCT) predicted by the McKee formula were off anywhere from 50.48% overestimate for the 5"x5"x48" box size to 69.36% underestimate for the 6"x6"x12" box.

The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board. It gives information on the ability of a particular board construction to resist crushing.

in the cross direction (CD), which he de fined as the parameter P m and parameters describing the bending stiffness of a cardboard box in two direc-tions D CD and D MD. McKee also used the param-eter P, meaning the perimeter of the box, a and b constants defined experimentally. The ratio of height H to the circumference P must be .1:7 » 0.143.

Good Morning, I'm glassing quad fins for the first time using the McKee Formula. My goal is to ride this shortboard in steep waist/head high waves, so pivot and hold are more important than drive. I followed the math and measurements and still have four days before I glass these on, so I thought it'd be wise to run this by the experts here. Also see, pic below: BOARD SPECS 6'2" x 19.8" x.

The general full form of the McKee equation is: CFL = a * ECT b * { (D MD D CD) } a-b * Z 2b-1 where: a & b = constants determined by experimentation ECT = edge crush test Z = perimeter of the box in cm CFL = Case failure load in N D = bending stiffness of the board

Paul Dudiak's 1969 McKee Mk12 was originally built-to-order for Tito Nappi, who owned Team Nappi Racing of Rockford, Illinois. The team's driver was Kurt Reinold, who drove it to eight SCCA Formula A National wins between 1969 and 1971. He also won numerous SCCA Divisional races and the SCCA Central Division Championship of 1970.

McKee's formula for BCT R.C. McKee and co-authors from IPC Appleton in 1963 [1] published a formula that has withstood the test of time as the simplest and most accurate predictor for box compression strength and is thus incorporated today in commercial box design software with various empirically based correction factors

Metric McKee Formula As input to the calculations, the Metric McKee formula requires the combined board Edge Crush Test (ECT) in kN/m, Caliper (CAL) in mm and Case Perimeter (PER) in cm. The Metric McKee formula is expressed as: Compression Strength = 1.82 x ECT x 1.0194 x CAL0.508 x PER0.492

McKee et al. started the development of the BCT prediction formula with the empirical formula for the failure load of a rectangular plate vertically loaded. The edges of the plate are unrestrained and so are said to be simply supported using engineering mechanics terms. A box is really 4 connected corners

The formula is the equation of a linear regression of the RCT and SCT values of samples with different basis weights. Lorentzen and Wettre provide a general equation which should be considered as a standard example and not used directly without a careful check of the parameters. RCT CD= 120 x SCT CD - 97 or approximately RCT CD= 95 x SCT CD (N)

The McKee formula for Compression Estimation The style common method of calculating a grade compression failure load (CFL, also sometimes noted as Box Compression Test Strength or BCT), is the McKee formula. This formula was developed in the 1960's and is named after one of it's main inventors.
