What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
This has been a wonderful resource for locating, filling out, filing and printing out documents. I don't understand how to make the most out of the system and wish I could get a little more help (for blondes). But overall, a great experience!

Initial rough start when my first document could not be converted to PDFfiller format & problems setting up an account password, but that is behind me now and application is working as advertised.
2016-11-21
The Popups that direct you to what to fill in are annoying. Would like to be able to turn off. Other than that Love PDF Filler Way better than my current management system's accords!
2017-08-02
Better and more powerful document management and editing on the web
Editing my PDFs without difficulty
This PDFfiller tool for online use is very useful since most PDF editors are paid and not all people can pay for such software. It also allows you to upload the documents you have in your Google Drive account, Dropbox and other tools
I do not find you disadvantaged, because you are covering the need of users who can not afford desktop software, to edit a PDF document

Timely help
PdfFiller came in handy when I filled out a form and they wanted all attached documents in pdf. I was able to quickly do the conversion without any issue and on time.

im amazed to learn about this!
I want to acknowledge the amazing Customer service you have here. How he handled well my concerns. And thank you because I accidentally activated 2 account under my two emails.. CUstomer service gave me so much consideration by cancelling one of the two accounts and process the refund of my cancelled account.
Thank you Sir for your assistance and patience. You are a competent Customer service manager. Keep it up.

By my own ineptitude I was having trouble printing a document. I thought I had to upgrade and then found out I didn't have to. So I reached out to get a refund and keep my original subscription and got that refund in MINUTES! I am a VERY happy, satisfied subscriber! And, I'm getting better at it :)

I needed to cancel my account but had…
I needed to cancel my account but had trouble doing so. The online customer support person Kara was so helpful! I am unemployed now like so many others and cannot afford the service any longer. But, once I get going again, this is the service I will sign up with. Wonderful service!

Fillable Forms
I wish you could download your fillable form to a website with all features included
You an edit PDFs and make forms fillable. It is easy to navigate and design your forms. I thought it was easy to add additional information to an existing pdf.
I would like to be able to download the form to my computer and post to my company website and have all features work.

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.
