The phrase "a low constraint" is correct and usable in written English.
It can be used in contexts discussing limitations or restrictions that are minimal or not very strict.
Example: "In this experiment, we applied a low constraint to allow for greater variability in the results."
Alternatives: "a minimal constraint" or "a slight restriction".
The single edge-notched tension (SENT or SE(T)) test uses a low-constraint specimen geometry to determine the elastic-plastic fracture toughness of relevant linepipe steels.
A low-constraint noun is one for which there is not a single common verb associate (e.g., for "house," the verb "live").
When applied to a structure with low constraint geometry, the standard fracture toughness estimates may lead to strongly over-conservative estimate of structural performance.
As a result, a new engineering tool to assess low constraint geometries with respect to brittle fracture has been obtained.
Hypothetically it could be that money withdrawn from the hole-in-the-wall is assigned to your everyday expenses and so has a low budget constraint.
In general, spacer sequences are more diverse than rDNA sequences because of a low functional constraint.
In order to cope with a low replication constraint, we needed to use an appropriate statistical method, called HTself [ 56].
A large proportion (47%) of SNP induced amino-acid changes and the Ka/Ks ratio calculated for all alleles with a complete ORF indicated a low selective constraint with respect to the high level of redundancy of the olfactory combinatory code and an ongoing pseudogenisation process, which affects dog breeds differently.
For a variety of reasons, structural members may be made of thin gage-materials with inherently low constraint to plastic deformation.
The latter affects the shape recovery strain through strengthening the matrix thus reducing the martensite strain which is more predominant under low constraint stresses.
