Thanks I have been using you and your service for years and if you ever want to run a marketing campaign to my 950,000 website members that are all real estate investors and agents please reach out to me.

PDFfiler allowed me to create a far superior MO Real Estate Disclosure form. It allowed me to edit to my heart's content, rather than scratching handwritten stuff out and ending up with such a mess that i had to hand write another copy. The end result was far more professional looking than a handwritten form. About a 5 minute learning curve and the software functioned perfectly. After editing, I was able to save the pdf to my computer, send it by email, print it, and some other stuff that I didn't use. PDFfiler can also get remote signatures.

PDFfiller saved me. I had forms to fill out for my college class and I could not get my computer to work. I could not edit them! Using PDF filler helped me get them all done. Thank you!

What do you like best?
PDF Filler is super simple to use. I love that you can just click where you need to put information (whether it’s a checkbox, words, etc) and it’s done. If you have a form that you use often you can even save it as a template so you don’t have to go back in and create new boxes each time.
What do you dislike?
I’ve had a few issues with the site being down but this only lasted for short periods of time. Otherwise, the product itself is fantastic.
What problems are you solving with the product? What benefits have you realized?
Instead of needing to print forms out, we are able to fill them out online, at a cost effective price. Saving us paper, ink and time.

Easy to edit pdfs using…
It was very easy to edit pdfs using this program. It has saved a lot of time effort to get this small change done on multiple documents.

PDF filler were fantastic.
PDF filler were great. I used the service when I needed and signed up the subscription service. I had a lot IRL things going on and forgot about it. They issued a refund anyways when I asked. Really great customer service from them when needed. Thanks to Jerome.

Super simple to use. There are only a few things that could use some tweaking like the sizing of the box for the fillable text could be a little simple to make smaller.

I purchased a change to my account in error.
I purchased a change to my account not knowing I was upgrading to a different service, one I didn't need and that I purchased in error. I immediately contacted pdfFiller and spoke to Kara. I explained my situation, and within minutes, she reverted my account back to the basic service and issued me a refund for the difference. She was extremely helpful and I'm extremely satisfied.

How do you find the critical crack size?
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.
What is critical crack size?
Critical crack size is the length at which a crack becomes unstable at certain applied stress. In an unstable crack, crack propagation, once started, continues spontaneously without an increase in magnitude of the applied stress. Fatigue failure occurs very rapidly once the advancing crack has reached a critical size.
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 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 critical stress intensity factor?
Critical stress intensity factor The stress intensity factor,, is a parameter that amplifies the magnitude of the applied stress that includes the geometrical parameter (load type). Stress intensity in any mode situation is directly proportional to the applied load on the material.
What is fatigue crack propagation?
The fatigue fracture of materials is caused by the nucleation and propagation of cracks under cyclic loading. However, structures can withstand an appreciable load in presence of cracks or failed parts are considered to be damage tolerant.
What is crack propagation?
Crack propagation is a process of evolutionary geometry driven by relatively high values and gradients in crack front fields and concomitant material damage.
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.
