How do I find what material properties are needed for a particular analysis in ABAQUS?

Read the relevant section in Chapter 6 : Analysis Procedures (User's manual Vol. I). This gives an overview about the analysis and has more information about the material properties. 
Read also the following sections in Chapter 17 : Materials Introduction of the ABAQUS User's manual.
  • Section 17.1.1 - Material Library : Overview
  • Section 17.1.2 - Material Data Definition
  • Section 17.1.3 - Combining Material Properties

Section 17.1.3 lists the material model combination tables. Several models are available to define the mechanical behaviour (elastic, plastic). 
Some material options require the presence of other material options. Some exclude the use of the other material options. For example *DEFORMATION PLASTICITY completely defines the material's mechanical behaviour and should not be used with *ELASTIC. 
Once you have all the relevant keywords to define the material properties consult the keyword Manual for each of the keywords. This will explain what data is required for each of the keyword.
