I've only done two documents, but so far I think it is a swell program! I have one more trustee that I'd like to add, will that cost more? We use the program for a charitable trust and we are unpaid. Thanks a lot, no matter what the answer is! I really like the program. MP

Customer Service Is Great
I used this service while at work and as a functional feature it is great, does what one needs it to do. However, as sometimes happens, I needed to charge this to my personal banking account at the time. When I left the company, I contacted their customer services team via their web based chat service and a kind lady named Monica answered my query. She was very helpful, diligent in helping me locate my details, and took her time to reassure me that the service subscription had ended and evening was a-ok. I know if I ever need to use this service I will come back, and part of the reason is because the customer care was absolutely spot on. Would recommend.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
How do you calculate crack growth rate?
Crack growth rate is defined as crack extension per cycle, the/DN. The crack growth rate is obtained by taking the slope of the crack growth curve at the crack length, a, as shown in Figure 2.
How do you calculate crack length?
(11) and the ASTM standard E399 that measures plane-strain fracture toughness. The equation used by the above ASTM standard to calculate the crack length is [1](20) a/W=0.99973.95U+2.982U 2 3.214U 3 +51.52U 4 113.0U 5 where(21) U=1/{1+[(ABV m /P)(4W/S)] 1/2} and Vm is the COD.
How do you find the critical crack length?
Regrouping gives the critical crack size for a given applied tensile stress: SCR = NCR/Y(c)0.5. The critical crack size, the largest flaw survives for a given applied stress is: Max=(NCR/Is)2. Once the critical stress is reached, fast fracture occurs with the upper limit of the crack tip velocity the speed of sound.
How do you measure crack size?
In addition, crack length can also be measured by using an optical microscope, an optical grid technology (Gucci et al., 1972, Must et al., 1976, James et al., 1981), an acoustic emission method (Gautama et al., 1994) and an ultrasonic method (Ahumada et al., 1983).
How does the stress concentration around a crack tip depend on crack geometry and size?
Note that the stress concentration factor is a function of the geometry of a crack or notch, and not of its size. As the radius of curvature approaches zero, like the tip of a sharp crack, the maximum stress approaches infinity and therefore stress concentration factors cannot be used for a crack.
What is fatigue crack growth?
A crack growth equation is used for calculating the size of a fatigue crack growing from cyclic loads. The growth of fatigue cracks can result in catastrophic failure, particularly in the case of aircraft. Fatigue life can be divided into an initiation period and a crack growth period.
What is stable crack growth?
Crack growth stability is called the resistance curve, or R-curve. For brittle materials, is a constant value equal to. For other materials, increases with increasing.
How do fatigue cracks initiate?
Pubs are areas that rise above (extrusion) or fall below (intrusion) the surface of the component due to movement of material along slip planes. This leaves tiny steps in the surface that serve as stress risers where fatigue cracks can initiate.
