Mechanics of Materials (MOM) Grant (NSF PD 08 1630) - Frequently Asked Questions

1) What was the Mechanics of Materials (MOM) grant opportunity?

The Mechanics of Materials (MOM) opportunity (Funding Opportunity Number PD 08 1630) was a National Science Foundation (NSF) discretionary research program within the Engineering Grants portfolio (CFDA 47.041). It supported fundamental, science-driven research in solid mechanics and the mechanical behavior of materials, focused on building and validating the core understanding needed to predict how materials deform, accumulate damage, and ultimately fail.

2) What agency offered this program?

The program was offered by the National Science Foundation (NSF).

3) What type of research did MOM aim to support?

MOM aimed to support fundamental research (not incremental applied development alone). The emphasis was on advancing the underlying mechanics and materials science foundations through rigorous theory, modeling, computation, and experiment.

4) What technical areas were within the program scope?

The program targeted research spanning theoretical, analytical, and computational solid mechanics, including model-based simulation and the development of constitutive models (mathematical descriptions of how materials respond to loads).

5) What are constitutive models in the context of this program?

Constitutive models are mathematical descriptions of material response under loading. The MOM description explicitly referenced models covering behaviors such as elasticity, plasticity, viscoelasticity, viscoplasticity, damage, and failure.

6) Did the program encourage linking microstructure to macroscopic properties?

Yes. A central theme was connecting structure to properties. Proposals were expected to address how nanoscale and microscale features (for example, grain structure, phase morphology, dislocation networks, interfaces, defects, and other microstructural states) control macroscopic mechanical response.

7) Was multiscale work encouraged?

Yes. The opportunity explicitly encouraged research linking behavior across both time and length scales, which commonly implies multiscale modeling frameworks and experiments designed to bridge atomistic or microstructural mechanisms to engineering-scale performance.

8) What material behaviors were emphasized (deformation, fatigue, fracture)?

The program emphasized fundamental research on deformation, fatigue, and fracture. This includes how materials permanently deform, how they weaken and crack under repeated or cyclic loading, and how cracks initiate and grow to catastrophic failure.

9) What kinds of mechanisms could be studied under the MOM program?

MOM highlighted interest in understanding molecular and microstructural states governing deformation, fatigue, and fracture. Examples mentioned include dislocation motion, phase transformations, interfacial decohesion, void nucleation and growth, and other mechanisms that drive damage evolution.

10) Were experimental approaches allowed, or was it theory-only?

Both experimental and analytical approaches were within scope. The description suggests that competitive proposals could combine advanced testing methods (to observe mechanisms and validate models) with mechanics-based analysis and predictive simulations.

11) What was the funding instrument for this opportunity?

The opportunity used the grant funding instrument.

12) What activity category did this program fall under?

It fell under the "Science and Technology and other Research and Development" activity category.

13) Was cost sharing or matching required?

No. Cost sharing or matching was not required.

14) Who was eligible to apply?

Eligibility was listed as unrestricted (open to any type of entity), subject to any additional eligibility details that would have been provided in the full NSF program announcement.

15) When was the opportunity posted?

The posting date was March 23, 2009.

16) Is this opportunity still active?

No. The listing was later archived on January 18, 2010.

17) Was this opportunity replaced by another NSF listing?

Yes. The archived record notes it was replaced by a different listing referenced as 10 1630.

18) What were the proposal submission windows?

Proposal windows were listed as recurring annual cycles, including September 1 to October 1 (annually thereafter) and January 15 to February 15 (annually thereafter). This reflects NSF-style submission periods rather than a single one-time deadline.

19) Does the archived record show expected awards or total funding?

The snapshot shows expected awards and estimated total funding as 0. This typically indicates the archived listing did not report totals in that dataset snapshot, rather than implying the program made no awards.

20) Where could applicants find the full program guidance when it was active?

The announcement referenced an additional information link labeled "NSF Program Description 08 1630," which would have contained the full program guidance, scope details, and proposal preparation instructions when the opportunity was active.

21) Who should applicants contact for trouble accessing the announcement electronically?

NSF directed applicants to Grants.gov support at grantsgovsupport@nsf.gov for issues accessing the announcement electronically.

22) What CFDA number was associated with this program?

The program was listed under CFDA 47.041.

23) How did the program distinguish itself from purely applied development?

The description made clear it was not aimed at incremental applied development alone. Instead, it sought advances in fundamental understanding of deformation and failure through rigorous theory, modeling, computation, and experiment.

24) What kinds of modeling approaches fit the MOM focus?

Based on the description, approaches within scope included theoretical and computational solid mechanics, model-based simulation, and constitutive model development, especially where models connect microstructure (nanoscale/microscale features) to macroscopic mechanical behavior and are supported by validation through experiment.

25) What is meant by "damage and failure" in the MOM description?

In this context, "damage and failure" refers to how materials accumulate internal degradation mechanisms over time and loading (for example, void nucleation and growth or interfacial decohesion) and how those processes lead to fracture, including crack initiation and crack growth to catastrophic failure.
