I like being able to fill in forms from online. $72 is too much for this as I only pay $30 for several other internet programs. There should be a refund.

Easy to use
It has made life much easier for my clients to receive what they need in a more timely manner
Easy to upload specific documents for editing.
When a field needs to be erased, the program always resets to add text. You have to re-select the erase button after each erased field.

Overall pleased, have a bit to learn for my use which is limited home tasks. I believe that initial access problems are resolved. I am sure that I could more easily accomplish the basic tasks that I have for PDF. Not pressing and I can fumble my way thru it.

Easy to use. I always send the doc to myself before emailing to final destination, just so I know what it looks like on the receiver's end. Adding a personal note to the email is a bit cumbersome--could be better explained of who sees what.

Had many of the forms I needed, however, surprised with researching NC business forms I found a 1997 form but not a 2000 form. Fortunately I can use a 2001 form for 2000 year.

Clueless in North Carolina!
I was clueless as to how to fill out the tax documents for my 1099 employees and your company walked me through it and I accomplished the task confidently.

What is COD test?
The Crack Tip Opening Displacement or COD Test measures the resistance of a material to the propagation of a crack. COD is used on materials that can show some plastic deformation before failure occurs causing the tip to stretch open.
What does Cod stand for?
COD. Acronym. Definition. COD. Center for Transit-Oriented Development.
What does Cod mean?
COD. The crack tip opening displacement (COD) test measures the resistance of a material to the propagation of a crack. COD is used on materials that can show some plastic deformation before failure occurs that causes the tip to stretch open.
What is crack blunting?
From Wikipedia, the free encyclopedia. Crack tip opening displacement (COD) or is the distance between the opposite faces of a crack tip at the 90° intercept position.
What is crack tip blunting?
One of the models that has been suggested for explaining the mechanism of crack growth under cyclic loading is the crack tip blunting model, in which crack growth is associated with blunting in the loading cycle followed by re-sharpening of the crack tip during unloading (Laird and Smith, 1962. Sellout, 1970. Suresh,
What is J integral in fracture mechanics?
The J-integral represents a way to calculate the strain energy release rate, or work (energy) per unit fracture surface area, in a material. The J-integral is equal to the strain energy release rate for a crack in a body subjected to monotonic loading.
Why COD test is required?
The crack tip opening displacement (COD) test measures the resistance of a material to the propagation of a crack. COD is used on materials that can show some plastic deformation before failure occurs that causes the tip to stretch open. Accurate measurement of this displacement is one of the essentials of the test.
What is singularity in fracture mechanics?
It is known from Chapter 3 that linear elastic fracture mechanics (LEFT) predicts an inverse square-root singularity at a crack tip. The stress singularity implies that the elastic stress will exceed the yield stress when approaching the crack tip, and consequently, a plastic zone develops in the crack tip region.
